Kathleen Ethier: Overall, I think youth are making better decisions, particularly about their sexual behavior and their.

Prior research has examined how heterosexual individuals define sex; however, these studies have rarely focused on sexual minority. The majority of paraplegics can achieve erection, and some have had fertile matings. It is obvious, therefore, that at least some of the more reflexive elements of the sexual behavior pattern Definition of sexual behavior organized at the Definition of sexual behavior level.

Sexual Behavior

Effects of cord transection in the female are not as clear, but whatever fragmentary elements of sexual behavior survive cord transection occur independently of hormonal stimulation. In neither sex is there anything resembling the normal pattern of sexual behavior in preparations with the brain stem sectioned below the level of the hypothalamus.

Small bilateral and midventral lesions in the hypothalamus of spayed female guinea pigs may eliminate all receptive behavior and mounting despite hormonal injection, which in the spayed unoperated female induces the complete estrous response Brookhart et check this out. In some females with slightly different lesions, receptive behavior is blocked but mounting behavior is unaffected.

In Definition of sexual behavior male guinea pig, hypothalamic lesions may eliminate all sexual behavior. However, some males may continue to mount following the operation. In most of these species, although not yet established for both sexes, one area in or near the hypothalamus controls pituitary function and thus governs sexual behavior Definition of sexual behavior and a second area exerts direct neural control over sexual behavior.

Destruction of the former eliminates sexual behavior by interfering with pituitary-gonadal axis function and therefore with output Definition of sexual behavior gonadal hormone necessary to normal sexual behavior.

Destruction of the latter area eliminates sexual behavior by interfering with a primarily neural mechanism Sawyer Lesions in the anterior portion of the hypothalamus in spayed female rats and guinea pigs have produced persistent receptivity, or estrus.

Such an operation releases the animal, to some extent at least, from gonadal hormone control of sexual behavior and thus produces a condition thought to exist normally in a number of primates, especially Definition of sexual behavior. A number of other lines of evidence implicate the hypothalamus as the region of the brain most directly involved in the control and integration of sexual behavior.

For example, hypothalamic implants of solid diethylstilbestrol dibutyrate produce in the spayed cat the full display of sexual behavior. Comparable implants in other regions of the Definition of sexual behavior or in subcutaneous tissue do not produce this effect Harris et al. Experiments involving electrical recording from hypothalamic areas in the cat have shown changes in potential associated with estrous reactions, and changes in electroencephalograph activity of the anterior hypothalamus have also been observed in association with mating behavior in the more info rabbit Sawyer When an electrode is permanently implanted in the hypothalamus of a rat and so wired that pressing a bar delivers a small electrical impulse to the brain area at the electrode tip, rats will repeatedly press the bar, thus obtaining electrical stimulation to the area.

Castration abolishes the bar-pressing response by the rat, but the response can be reinstated by injecting the castrate with testosterone Olds Such a demonstration tells us little about sexual behavior but implicates the hypothalamus in behavior that is dependent on a gonadal hormone.

In a now classic experiment, Kliiver and Bucy performed bilateral temporal lobectomies on monkeys and reported a broad constellation of behavioral changes, including heightened sexual activity, following the operation.

Hypersexuality Definition of sexual behavior later reported following destruction of the amygdaloid more info and overlying pyriform cortex in lynxes, agoutis, cats, and monkeys. Castration of male cats resulted in elimination of hypersexuality. In lower mammals, including the cat, complete removal Definition of sexual behavior the neocortex of the female does not Definition of sexual behavior sexual receptivity, although the quality of the response may suffer.

In male rats comparable decortication eliminates all sexual behavior, and these males show no Definition of sexual behavior of arousal in the presence of an estrous female. Partial decortication in the cat may eliminate successful mating behavior because of loss of sensory-motor integration, but the operation need not interfere with sexual arousal Beach In primates the cortex may play a major role in integration of sexual behavior.

In general, the more important learning and memory are in sexual see more, the more important the neocortex is likely to be. It is apparent that control of Definition of sexual behavior behavior is not vested in any single brain area. The evidence suggests rather that the entire nervous system is involved Definition of sexual behavior the display of the normal pattern of sexual behavior.

Although it has been pointed out that differences in patterns of sexual behavior are associated with differences in genetic background, this does not preclude the importance of experiential factors in determining the particular pattern displayed by the individual.

The limits to which experience can modify the behavior pattern are, however, largely determined by genetic factors. In studying the influence of experiential factors on mating behavior, we are indirectly examining the variability allowed by genetic endowment.

When males from two inbred strains of guinea pigs were separated from their mothers at the age of 25 days and reared in isolation, they did not display normal mating behavior patterns when tested as adults. For isolation to produce comparable effects in male guinea pigs of a heterogeneous stock, the animals had to be isolated beginning at 10 days of age. The experiment demonstrates the influence of genetic and experiential variables in determining patterns of sexual behavior. However, mother-deprived infants, if given an opportunity to interact with peers, develop essentially normal patterns of sexual behavior.

The manner in which peer interaction fosters development of normal sexual behavior remains to be demonstrated. Female guinea pigs and rhesus monkeys reared in isolation also show deficiencies in reproductive behavior.

Despite the bizarre social behavior and abnormal sexual behavior displayed by the isolated female rhesus, a number have mated with particularly capable males and have delivered viable young. It should be noted that the behavioral deficiency is not attributable to gonadal hormone deficiency Definition of sexual behavior the isolated monkey or guinea pig.

Although the exact nature and extent of the effects of click on sexual behavior have not been determined for the male rat, available evidence suggests that the impairment is not as profound as it is in the monkey Zimbardo A wide variety of experiences are capable of modifying sexual behavior in addition to the method of rearing just discussed. What has been demonstrated is that sexual behavior, in general, Definition of sexual behavior subject to modification just as other aspects of Definition of sexual behavior can be modified by varying experience.

Thus despite heritability of sexual behavior patterns, dependence on hormonal stimulation, and the spinal reflex contribution to patterns of sexual behavior, the complete pattern can be blocked, enhanced, or modified by social and situational experience. Definition of sexual behavior extent to which it can be modified by experience varies primarily with the species, sex, and age of the Definition of sexual behavior.

Sexuality may be experienced and expressed in a variety of ways, including thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles, and relationships.

Social scientific writing on sexual behavior over the past century falls in three categories: It is now commonly accepted that the frequencies and techniques of sexual behavior vary widely among individuals and among religious, class, ethnic, educational, age, and sex categories in the same society Definition of sexual behavior et al.

As producers of literature on sexual behavior, social scientists check this out easily outnumbered by physicians, psychologists, physiologists, theologians, and philosophers, among others. The present article, rather than restricting itself to studies by social scientists, will conceptualize the content of this diverse literature from a social science perspective.

These materials will be examined in terms of the social meanings of sexual behavior, the way the sexual enters as Definition of sexual behavior component of social roles, the social norms governing recruitment to these eroticized roles, and their articulation with networks of the noneroticized roles that constitute some major social institutions.

Reference will be made to social organizational arrangements for facilitating or inhibiting enactment of these roles. Sexual behavior participates in social action by contributing a motive, or a driving force of that action. Ratzenhoferan early theorist of the sociology of sex, saw all motives of social contact as modifications of either the instinct of self-preservation or the sexual instinct.

Moreover, as a component of social action, sexual behavior is also a way of expressing and conveying both individual and social meanings; that is, the meaning is not Definition of sexual behavior that which an individual attributes to his act but also that which society has come to apply to the act Thomas These are by far the most popular scientific studies of sex, as measured by sales and published critical reviews.

From a physicalist point of view, the presumption that all acts engaging the genitals are alternative ways of tapping the same reservoir of physiological energy justifies drawing them under the same rubric. Social science analyses of sexual behavior are primarily concerned with coital acts, Definition of sexual behavior homosexual and heterosexual, which involve a relationship between human beings and are thus qualitatively different from other sexual behavior. Masturbation, nocturnal emissions, and bestiality claim social science attention only insofar as they affect either the occurrence of coitus or its meaning or become the object of institutional concern.

According to this view, the energy problem is interwoven with that of the social meaning of sexual acts. Freudian theory of the economy of the libido Definition of sexual behavior the notion of sublimation to designate the rechanneling of sexual energy into cultural activities by shifting the object of cathexis; thus the theory interweaves motivational and meaningful aspects.

Sexual behavior contains a nonverbal language through which an individual expresses and conveys meanings; sensory exploration Definition of sexual behavior gestures outweigh words as sign and symbol vehicles. Removal of clothing beyond see more degree necessary for coitus itself exemplifies the significance of tactile communication. Any sexual act may carry several social and personal meanings. For example, a morning erection may express unconscious concerns about death rather than sex Definition of sexual behavior Ford and Beach studied sexual behavior between species and across cultures, yet they granted priority to the physicalist approach by classifying sexual behavior according to modes of stimulation of the genitals.

A consequence of this physical perspective is their tendency to measure the cause of sexual behavior in terms of tension reduction and to designate procreation as its principal social function. The procreative function loses its centrality for a social psychology of human Definition of sexual behavior behavior in view of the empirical fact that less than one in a thousand human coital acts results in pregnancy and fewer are intended to do so Foote However, for sociology, the part of sexual behavior that is, in fact, procreative becomes significant because of both the demographic consequences and the institutional and organizational arrangements that become necessary for the birth and rearing of offspring Ellwood Sexual behavior as a role component, that is, as a component of social action under decisional and normative control, distinguishes human from animal sexuality.

A social role—such as that of lover, of prostitute or client, of husband or wife, of young male delinquent or adult fellator A.

This is what has been described as a transformation of sexuality into Eros Marcuse Sexuality becomes meaningful to the actor, and may be understood by Definition of sexual behavior observer, in the context of these other aspects of the personality. An eroticized social role may be articulated with other roles in the social structure; for example, the role of the prostitute in her relation with a client may be meshed with her relatively nonerotic check this out in her relation with her madam or other employer.

This perspective on role articulation follows Malinowskiwho advocated an anthropological perspective that does not treat sex as a mere physiological transaction but studies its implication for lovemaking, its function as the nucleus of the family, the spells and magic that grow up around it, its effects upon, and how it is affected by, the legal system and the economic system.

The variety of sexual meanings is, in part, Definition of sexual behavior on other aspects of the role—that is, on other norms, affects, or meanings that define that role or other roles with which it is articulated in a personality or in a society. Kirkendall described how sex, while it may advance a deep interpersonal relation, may be exploitative as part of a casual relationship.

With prostitutes, the relationship itself becomes the instrumental servant of its sexual component. Even in advancing a deep relation, however, sex may assume special meanings associated with the broader meaning of that relationship. Thus sex may be a weapon to destroy, a mode of defense, a bargaining point, or a form of self-assertion; negatively, it may be a form of self-denial Frank Components of an eroticized role may be malintegrated.

Sexual behavior inconsistent Definition of sexual behavior personal Definition of sexual behavior standards may engender an internal struggle manifested in guilt feelings. If strains of this type become widespread, social standards may be readjusted I. Reiss Recruitment of partners to an eroticized role is governed by considerations of personality, social norms, and societal mechanisms of control.

Personality variables affect the desire and ability of an individual to seek, as well as his desirability as, a sex-role partner. In the preparatory stage, an individual must be able to respond to excitation from internal and external psychological stimulation.

This requires sensory, intellectual, motor, and glandular contributions to mechanisms of arousal. An individual must experience impetus to penetrate or desire to be penetrated, want to continue inplay, and, at culmination, experience orgastic peristalsis of genital structures.

Much depends upon ability to tolerate regression in the service of the ego Fried Disturbances of sexuality are commonly classified in terms of frigidity, low potency, preference for masturbation or Definition of sexual behavior sexual perversion, hypersexuality, and lack of sexual interest Eisenstein Special personality groups vary in interest in eroticized roles.

Most of the erotic impulse of idiots is directed toward themselves and the remainder to objects of the same sex Potter Alcoholics lack sex interest, because, it has been argued, of repressed homosexuality Levine The aged tend to lose motivation for coitus Armstrong The evaluation of personal characteristics in recruitment is relative to the persons involved; that is, an individual not desirable to one partner may be desirable to Definition of sexual behavior. For example, males generally prefer shorter females, Definition of sexual behavior females generally prefer taller males.

Women who want men near their own height, it has been argued, are expressing a need for ascendancy. Similarly, males who seek taller women are said to be seeking to possess the forbidden parent figure Beigel Social norms prescribe and proscribe which social types may recruit one another.

Definition of sexual behavior Ellisfor example, wrote that in choosing a mate we tend to seek parity of racial and anthropological characteristics together with disparity of secondary sexual characteristics and complementarity of psychic characteristics. Under control of instinct, Nice mature porn movies rarely depart from parity of species and disparity of secondary sexual characteristics.

Mongrelization may be induced among domesticated animals but is extremely rare among wild animals despite opportunities. Man can, and sometimes does, engage in relations that the Definition of sexual behavior constitutionally directed animals would refuse. Man may disregard species parity and practice bestiality, disregard secondary sexual disparity and practice homosexuality, and disregard psychic complementarity and establish neurotic sex relations.

On the other hand, man may refuse relations because of sexual style, the status of the partner, or the beauty of the partner—a parity irrelevant to the animal.

For man, the power of the social over biological determinants extends to the very definition of gender. Money et al. Rules for recruitment to coital relations in general parallel, but source not completely overlap with, those governing marital recruitment. Laws of exogamy define the inner social limits for recruitment of a marital Definition of sexual behavior. These are extensions of the incest taboo, which is a nearly universal taboo, with exceptions only in such cases as the Egyptian royal family, where brother-sister marriage was permitted, or among Azande nobles, where father-daughter marriage has been permitted.

Laws of endogamy define the outer social limits. In human relations, however, endogamy controls potentially fertile relations within the same species. A number of individuals are virtually precluded from recruitment to eroticized heterosexual roles.

This is the case with institutionalized populations in prisons or mental hospitals. Likewise, occupational conditions Definition of sexual behavior separate individuals from the opposite sex.

Is it natural to have like that? Is it natural to have it like that?

Hobos, being homeless, have less access to women, and thus they tend to frequent the lowest Definition of sexual behavior prostitutes and to practice homosexuality. Social control of eroticized role recruitment contributes to the maintenance of the social structure; if society lacked such controls, random mating could disrupt the familial and economic lines of stratification of a society.

Moreover, social control of recruitment may enable one social group to dominate another through its power to allocate sexual occasions and facilities. It may also be an internally integrative Definition of sexual behavior, as it is among celibate monastics.

According to Definition of sexual behaviorsuch control is necessary to manage a smoldering antagonism that exists between the sexes as groups. Communication employed for recruitment to the eroticized role parallels the communication of arousal in the sex act. Token Definition of sexual behavior announces sexual availability. Erotic communication relies heavily on movement, such as the inviting movements of the dance and the arousing tactile movements during coitus.

Odors founded in the natural capryl odors and supplemented at the human level by perfumes act upon the deeper levels of consciousness Bloch Cosmetic means of communicating sexual interest include painting and tattooing as well as sexual mutilation. Socially stylized ceremonies of fertility or initiation may announce availability and effect arousal.

A few rites, such as subincision, announce sexual availability but reduce sexual enjoyment or arousal potential for the Definition of sexual behavior Allen ; Westermarck Verbal communication supplements sensory communication in sexual behavior.

Speech is so closely identified with sexuality that in some cultures it is forbidden or restricted between persons who are socially precluded from engaging in sexual relations Baker The more intimate a sexual matter, the less the likelihood of communication about it to nonerotic role partners. In many societies, socially structured mores about erotic communication bar young people from arousal and consummatory opportunities.

Sexual norms may be learned inferentially by the young or by new social groups, such as immigrants, by observation of behaviors lacking primary erotic meaning, such as forms of dress and of association between the sexes Klausner Classified newspaper advertising and a specialized journalism directed to erotica have long been used for the recruitment of both heterosexual and homosexual partners. Deviant subgroups Click at this page private signaling systems to cue a potential partner without revealing themselves to noninitiate spectators.

For example, homosexuals may wear peculiar clothing the definition of which changes from time to timeintersperse their speech with a special argot, or perform certain gestures.

They may position themselves to receive such signals by frequenting known haunts. Society not only exerts control over the recruitment of role partners but also attempts Definition of sexual behavior control the types of sexual behaviors enacted and the occasions for their enactment.

A quasi-formal control mechanism is exemplified among the Mondurucu by the gang rape to force a recalcitrant click to submit to male authority Murphy Norms also define those behaviors to which it is legitimate to recruit.

Early studies of sexual behavior treated cross-cultural comparisons descriptively, presenting various behaviors, sexual art, and technical devices as curiosities Moll ; Krafft-Ebing ; Bloch Correlations between sexual behavior and the overarching cultural Definition of sexual behavior allow inference about the types of sexual behaviors to which recruitment is approved in Definition of sexual behavior cultural situations; that is, recruitment norms vary with the ethos.

In matristic periods, dominated by a mother religion and exemplified by England after the first millennium, people have a horror of incest and are permissive regarding sex. Social control may be exerted by concrete organizational arrangements.

Like food, sex is an important part of our lives. From an evolutionary perspective, the reason is obvious—perpetuation of the species. Definition of sexual behavior behavior in humans, however, involves much more than reproduction.

Click at this page section provides an overview of research that has been conducted on human sexual behavior and motivation. This section will close with a discussion of issues related to gender and sexual orientation.

Much of what we Definition of sexual behavior about the physiological mechanisms that underlie sexual behavior and motivation comes from animal research. Surprisingly, medial preoptic lesions do not change how hard a male rat is willing to work to gain access to a sexually receptive female Figure 1. This suggests that the ability to engage in sexual behavior and the motivation to do so may be mediated by neural systems distinct from one another.

Figure 1. A male rat that cannot engage in sexual behavior still seeks receptive females, suggesting that the ability to engage in sexual behavior and the motivation to do so are mediated by different Definition of sexual behavior in the brain. Jason Snyder. Animal research suggests that limbic system structures such as the amygdala and nucleus accumbens are especially important for sexual motivation. Damage to these areas results in a decreased motivation to engage in sexual behavior, Definition of sexual behavior leaving the ability to do so intact Figure 2 Everett, Figure 2.

The medial preoptic area, an area of the hypothalamus, is involved in the ability to engage in sexual behavior, but it does not affect sexual motivation. In contrast, the amygdala and nucleus accumbens are involved in motivation for sexual behavior, but they do not affect the ability to engage in it. Although human sexual behavior is much more complex than that seen in rats, some parallels between animals and humans can be drawn from this research.

The worldwide popularity of drugs used to treat erectile dysfunction Conrad, speaks to the fact that sexual motivation and the ability to engage in sexual behavior can also be dissociated in humans.

Animal sexual behavior is but one aspect of the total pattern of reproductive behavior.

Moreover, disorders that involve abnormal hypothalamic function are often associated with hypogonadism reduced function of the gonads and reduced sexual function e. For example, many animals show no sign of sexual motivation in the absence of the appropriate combination Definition of sexual behavior sex hormones from their gonads.

Physicians were considered authorities on all issues related to sex, despite the fact that they had little to no Definition of sexual behavior in these issues, and it is likely that most https://xwoodporn.com/pierced-pussy/article-mature-spanish-porno.php what people knew about sex had been learned either through their own experiences or by talking with their peers.

Convinced that people would benefit from a more open Definition of sexual behavior on issues related to human sexuality, Dr. Alfred Kinsey of Indiana University initiated large-scale survey research on the topic Figure 3. The results of some of these efforts were published in two books— Sexual Behavior in the Human Male and Sexual Behavior in the Human Female —which were published in andrespectively Bullough, Figure 3.

In men, the duration of the refractory period can vary dramatically from individual to individual with some refractory periods as short as several minutes and others as long as a day. As men age, their refractory periods tend to span longer periods of time. Figure 4. This graph illustrates the different phases of the sexual response cycle as described by Masters and Johnson. Furthermore, they determined that the vagina is a very elastic structure that can conform to penises of various sizes Hock, Figure 5. Till Krech. Issues of sexual orientation have long fascinated scientists interested in determining what causes one individual to be heterosexual while another is homosexual. For many years, people believed that these differences arose because of different socialization and familial experiences. Genetic and biological mechanisms have also been proposed, and the balance of research evidence suggests that sexual orientation has an underlying biological component. In aggregate, the data suggest that to a significant extent, sexual orientations are something with which we are born. Regardless of how sexual orientation is determined, research has made clear that sexual orientation is not a choice, but rather it is a relatively stable characteristic of a person that cannot be changed. Claims of successful gay conversion therapy have received wide criticism from the research community due to significant concerns with research design, recruitment of experimental participants, and interpretation of data. As such, there is no credible scientific evidence to suggest that individuals can change their sexual orientation Jenkins, Robert Spitzer, the author of one of the most widely-cited examples of successful conversion therapy, apologized to both the scientific community and the gay community for his mistakes, and he publically recanted his own paper in a public letter addressed to the editor of Archives of Sexual Behavior in the spring of Carey, In this letter, Spitzer wrote,. I was considering writing something that would acknowledge that I now judge the major critiques of the study as largely correct. I believe I owe the gay community an apology for my study making unproven claims of the efficacy of reparative therapy. Becker, , pars. Citing research that suggests not only that gay conversion therapy is ineffective, but also potentially harmful, legislative efforts to make such therapy illegal have either been enacted e. Read this draft of Dr. Many people conflate sexual orientation with gender identity because of stereotypical attitudes that exist about homosexuality. In reality, these are two related, but different, issues. Generally, our gender identities correspond to our chromosomal and phenotypic sex, but this is not always the case. When individuals do not feel comfortable identifying with the gender associated with their biological sex, then they experience gender dysphoria. Gender dysphoria is a diagnostic category in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders DSM-5 that describes individuals who do not identify as the gender that most people would assume they are. This dysphoria must persist for at least six months and result in significant distress or dysfunction to meet DSM-5 diagnostic criteria. In order for children to be assigned this diagnostic category, they must verbalize their desire to become the other gender. Approximately 1. Many people who are classified as gender dysphoric seek to live their lives in ways that are consistent with their own gender identity. This involves dressing in opposite-sex clothing and assuming an opposite-sex identity. These individuals may also undertake transgender hormone therapy in an attempt to make their bodies look more like the opposite sex, and in some cases, they elect to have surgeries to alter the appearance of their external genitalia to resemble that of their gender identity Figure 6. Transgender people who attempt to alter their bodies through medical interventions such as surgery and hormonal therapy are called transsexual individuals. Not all transgender individuals choose to alter their bodies: These various implantation neurohormonal experiments have shown that the sex hormones are not clearly sex specific, but often paradoxical in their neurobehavioral effect. Other chemicals may be found capable of producing their effects. The ultimate possible application of this new breakthrough in dealing with psychosexual pathology cannot be foreseen at the present time. A third approach in neurohormonal research is to alter the neural organization of later sexual behavior by injecting hormones into the pregnant mother or newborn animal guinea pig and rat. The findings of several investigators converge, tentatively indicating that, dependent on species differences in gestational age at birth, there is a critical period around the time of birth when androgen has an organizing effect on neural centers in the hypothalamus. Androgen is thus implicated as an active organizer of the sexual control system, both in terms of reproductive cycles and sexual behavior. At a critical period earlier in embryonic life, androgen is an active organizer substance without which the internal anlagen of the female reproductive anatomy persist and the anlagen of the external organs feminize Jost One conjectures a relationship here with the greater vulnerability of the male to disease and death, which would create an unequal sex ratio except for the fact that males are born to females. One conjectures also a connection with the fact that psychosexual disorders have a higher incidence in men than in women, with some of the psycho-sexual anomalies, like fetishism, voyeurism, and exhibitionism, being to all intents and purposes unheard of in females. The higher incidence of psychosexual pathologies in the male may be related to a sex difference in erotic arousal patterns. This difference is manifested in the greater capacity of the male to be aroused erotically and genitopelvically, and to be ready for immediate release, by pictorial and narrative imagery. Such stimuli arouse the female sentimentally to want her lover or husband; but she is dependent on direct tactile stimulation, more than the male, for the arousal of genitopelvic eroticism. There is some evidence in the psychology of hermaphroditism that the male arousal pattern may be neurally organized under the influence of androgen in fetal life. It will be for further research to determine whether the development of psychosexual pathology in the male may be rooted in part in imperfect or faulty neurohormonal organization at this early period. One thing already quite clear in the evidence of hermaphroditism is that a masculine type of arousal pattern is perfectly compatible with entirely feminine cognitive content and imagery of eroticism that parallels the sex of assignment. Perceptual stimulants to sexual arousal and the reproductive cycle vary with the species. The relation between light stimulation and the release of pineal hormones is being newly investigated in the rat. Acuity of the sense of smell in human females Money b is regulated by estrogen and varies with the menstrual cycle. Its relation to other cyclic sexual phenomena or to sexual disorder has not been investigated. Odor may be the agent responsible, in the macaque monkey, for fluctuation in male sexual behavior in rhythm with the female menstrual cycle, as described by Michael and Herbert In addition to benefiting from the new neurophysiological techniques, contemporary sex research has also benefited from the new techniques in genetics. The relevance of the new findings to the theory of psychosexual pathology has been chiefly negative: Affected individuals are phenotypic males with an extra X chromosome. There appears to be an unusually high incidence of psychopathology, including sexual disorders, that develops in association with the syndrome Money a. Otherwise genetics cannot be directly implicated in psychosexual ambiguity Money b. Disorders of sexual psychology express themselves in full in adolescence after the advent of hormonal puberty brings erotic functioning to maturity. It is probable that the majority of such disorders have their initial origins in faulty psychosexual differentiation persisting from early childhood. Later error or regression of differentiation are also possible, as is simple arrestment in psychosexual growth. Faults, errors, regression, and arrest of development have, on the one hand, a chronologic origin and, on the other hand, an etiologic origin. The chronologic origin may fall within a critical period, with resultant immutability or refractoriness to change. The etiologic origin may be single or multiple. An etiologic factor may by itself represent only a potential vulnerability to psychosexual disorder, materializing only when in combination with another factor or factors. Thus a genetic vulnerability may materialize only when the behavioral environment conspires appropriately. Etiologic considerations include genetic, gestational, metabolic, nutritional, toxic-infective, traumatic, behavioral-experiential, and social-interactional factors. Benjamin, H.

Journal of Mental Science Society of Medical Psychoanalysts Homosexuality: A Psychoanalytic Study , by Irving Bieber et al. Deviance in general, and sexual deviance in particular, presents the scientist with extremely difficult problems of definition and analysis. Sexuality is, perhaps more than any other aspect of human behavior, mingled with moral imperatives, conscious fantasy, and unconscious desires, all of which combine to trouble even most scientific observers Trilling ; Rieff The recognized necessity not to mention utility of sexual behavior makes the problem of establishing cutoff points beyond which the interaction of actors, acts, and contexts may be denned as deviant even more obscure than it is in other areas of behavior. The positive functions of the sexual impulse for society have indeed resulted in advocacy, by small minorities to be sure, of behavior that is widely conceived of as immoral, antisocial, or immature. In a discussion of sexual deviance it would be useful to consider cross-cultural data. However, there is a minimum of scientifically comparable data about sexual behavior available, even from European countries see Kinsey et al. Ford and Frank A. Beach In this article the cultural focus is mainly the United States; other industrialized Western societies are treated with less precision. Sexuality has the curious distinction of being the only biological drive that has been regulated in nearly all its physical manifestations. Although these prohibitions are often attributed to the prudery of the nineteenth century, it is clear that they are of considerably more ancient origin. All the sexual acts that are currently legislated against in the criminal law owe their stigma to the Judaeo-Christian religious tradition. These very early prohibitions remain with us today, when, in a very different context and serving other functions, they still operate to shape training for sexual behavior, attitudes toward this behavior in both the self and in others, and the institutional structures that are meant to control it. Although it is possible to find some situation in which any act might be described as deviant, it is very difficult to approximate the universal condemnation of deviant sexuality in any other area of behavior. Particularly impressive is the discrepancy between the system of sexual taboos, as expressed in both the law and individual attitudes, and the corresponding systems of overt behavior. From the survey research on sexual behavior in the United States see Kinsey et al. There is a considerable bias toward greater male participation in deviant behavior than female, but both sexes include a relatively large number of taboo violators. In addition, for the relatively short period for which data are available these rates of participation have remained remarkably stable, indicating that they are outgrowths of normal social operation rather than the consequence of upheaval or disorder. There is evidence that although there is a wide distribution of these different forms of sexual behavior, attitudes toward them remain relatively repressive see Wheeler and I. Reiss for attitudes toward premarital coitus. Repressive attitudes can be held even by those who habitually participate in deviant sexual activities, as has been shown by a study of homosexually experienced males Gebhard et al. Given the strong taboos against most of its manifestations, it is very difficult to determine why so much deviant behavior occurs. However, it is important to point out that although the taboos are strongly expressed, the sanctions are not as strongly invoked. Part of this is probably due to the sheer strength of the biological drive. It is important not to assume that all of the variance in sexual behavior is attributable to social and psychological factors, since there is still a general lack of data on the interaction between these elements and the biological substrate. Some of the differences between the overt sexual behavior of males and females may be due to basic hormonal and other biological characteristics as well as to differential socialization practices Kinsey et al. In the first few years of life, interactions between parents and children, predominantly at the nonverbal level, build a basis of sexual capacities on which later verbal learning concerning normative standards of behavior about these capacities is overlaid. Furthermore, the majority of adult-child interaction having impact on the learning of sexual behavior is not conceived of by the adult as having any relevance to the ultimate sexual adjustment of the child. Such adult-child interaction is permitted or even encouraged, provided that its latent sexual content is not explicitly labeled or identified for what it is; as soon as it is so labeled and acknowledged it falls within the purview of one prohibition or another. It is the ambiguity of early sexual instruction that seems to be important. The setting of the capacities and directions of sexual behavior occurs at an unrecognized and unconscious level, whereas the conscious attitude instruction not only takes place sporadically but frequently is unrelated to the development of the behavioral systems that the attitudes purport to control. One of the functions of language is that of helping the child to order and to control the world; apparently, what happens in the formation of sexual attitudes is that words are not supplied to the child to enable him to label and come to grips with his feelings and desires. In such a context the sexual zone is left to the imagery and fantasy often noted in childhood and adult sexuality. Examination of the social structures that control sexual learning after childhood makes apparent the imprecision and vagueness of the connections that exist between behavior on the one hand, and attitudes toward such behavior, on the other. A certain amount of sexual display and exploration occurs during the prepubertal years among members of both sexes, but the significant element is that unless this activity is noted and defined negatively by adults or unless the behavior takes place between an experienced person and a child, there is little impact on the child. In addition, there is not necessarily any organization of sexual learning as a result of these experiences. A child who has had prepubertal experience similar to coitus may be unaware of the connection between this behavior and other sexual activities. During puberty the significance of the genital sexual function becomes more apparent, but young people who become involved in sexual behavior do so in considerable ignorance. In the culture of adolescence the folklore of sexual experience is rife with error and misperception. Males and females get together sexually often as the result of accident, and frequently they do so for nonsexual motives. Because of the strength of the sexual drive and the ambiguous circumstances under which its control is learned, much adult sexual behavior takes place under conditions of mutual misunderstanding. Although there is a transfer of learning from one sexual experience to another, there is rarely a successful dialogue between male and female about such matters of mutual sexual interest. The bulk of sexual communication is gestural and, between persons with some mutual experience, often ritual in character. Many sociologists have described deviance as being learned in a socially well-defined initiatory system for example, the predelinquent subculture or even lower-class society in toto and maintained in a supportive social setting for example, the drug-addict community. For most sex offenders, and for nearly all classes of sexual behavior that are described as deviant, a prior socially structured learning system apparently does not exist. In addition, the notion that deviant behavior must be maintained through subcultural supportive systems is difficult to apply to the problem of sexual deviance, although in some types of sexual deviance such systems do appear. Sexual deviance seems to be of three general types. The first is situation-specific deviance that is normatively disvalued or at least not valued positively but which nonetheless serves generally useful purposes and is so ubiquitous that sanctions are applied to only a minority of those involved. This type of deviance involves no articulated system of social roles. The second type of sexual deviance consists of those forms that have supportive social organizations either for the purpose of gathering sexual partners or clientele together, or for social support in deviance, or for both purposes. Finally, there is a large body of deviance pedophilia, incest, and so on , which is condemned and against which strong sanctions are invoked, that does not seem to be learned in recognizable deviant social structures and that does not have a socially organized performance system. Masturbation and premarital coitus are primary examples of behavior that is generally denned as deviant but that does not involve the application of sanctions unless the perpetrators are, by some mischance, apprehended or there is some untoward consequence, such as pregnancy or venereal disease. Solitary masturbation is not against the law; premarital coitus may be, especially if either party is legally a minor, but even so prosecutions are comparatively rare. The perceived utility of masturbation as a male adolescent sexual outlet with few social consequences in comparison to coitus may account for the decreasing stigma attached to it. It seems to be related to other behavior defined by social class and characterizes males who assume middle-class occupational roles Kinsey et al. Premarital coitus is culturally valued for males especially within the pro-masculine lower-class culture, accounting for its prevalence and the lack of invoked sanctions I. Reiss ; Whyte Both masturbation and coitus are class-linked and seem to be the most appropriate responses to the impact of the sexual drive after puberty in the male. For females premarital coitus is connected with impending marriage and a love relationship; thus, the behavior is defined as proper in a situation-specific way. Masturbation in females seems to have no class linkages at all. In general these activities have a smaller incidence and a lower frequency among females than among males, possibly because of both hormonal differences and differences in socialization. The second type of deviant sexual behavior is that which involves supportive social structures either for the purpose of entry into the system of behavior or for the maintenance of the individual in the behavior. This type of behavior comprises homosexuality and prostitution. It is only female prostitution that has all the elements of a deviant subculture similar to that of drug addicts or juvenile delinquents Davis ; Kinsey et al. In this situation the stigma for the sexual behavior is attached to the prostitute, and the legal sanctions for the behavior are leveled primarily against her, secondarily against the abetting persons pimps, madams , and exceedingly rarely against the customers or against agents of law enforcement who may condone her activities. Prostitution develops organized forms primarily because of its commercial aspect and because of the character of the enforcement program that is designed to control it. For the most part, recruitment of individuals for homosexual experience does not occur through a social system organized for that purpose. Unfortunately, studies of the etiology of homosexuality have been most unsatisfactory in their attempts to locate the crucial early experiences that are salient Money Some etiological studies have focused on biological and especially genetic factors, sometimes mediated through hormonal anomalies. But even though there have been some studies of twins Kallman ; and some work has been done on hormonal factors Kinsey , the most persuasive discussions of early factors in the development of a homosexual commitment have been couched in the psychoanalytic tradition or in certain variants of it Society … ; Ovesey As a result his relations with females are blighted because of his fears of paternal revenge for his incest, which remains forever unconsummated. Other explanations in this tradition are less metaphorical in their language but still focus upon seductive mothers, detached fathers, lack of a male figure in the home, and the like. Unfortunately the bulk of the populations who have been the source of the data in these reports have been examined in the course of psychotherapy or other treatment, creating a situation in which pathology and homosexuality are inextricably confounded. During the pubescent years there is a good deal of minor homosexual experimentation that accounts for nearly all of the homosexual activity of the predominantly heterosexual portion of the population. Thus, it can be predicted that about one in three of all males born in the United States will at some time have a homosexual experience to the point of orgasm; however, about 85 per cent of those having such experience will do so only in their adolescent years. Among females the proportion who ever have a homosexual experience will be somewhat smaller, but once again most of them will confine the experience to adolescence Kinsey et al. The factors that distinguish those who go on to adult homosexual commitments from those who experience homosexual acts only as transient parts of adolescent development are still unknown. However, it is known that males often develop strong sexual interests in other males without knowing that there is such a thing as homosexuality. This process occurs more frequently in specialized sexual interests such as transvestism and fetishism. The realization of being homosexual occurs in a variety of ways: It is after the point of conscious admission that one is a homosexual—an admission that ranges from the traumatic to the delighted—that the search for sexual partners begins. This search usually requires entry into the world of homosexual bars, development of the argot of homosexual life, and gradual learning of the modes of approach and retreat that are related to the satisfaction of sexual needs. These studies have begun to outline the processes of adult socialization that are involved in the development of the homosexual commitment. The extant literature is nearly exclusively concerned with the male homosexual; the literature on the lesbian is both scanty and scientifically inadequate. In general, discussions of the lesbian tend to focus on the similarities between male and female homosexuality and to see one as the mirror image of the other—that is, to see male homosexuals as imitations of females and female homosexuals as imitations of males. Not all homosexuals are regular members of the homosexual community and many of them never involve themselves in this social milieu at all. The development of homosexual contacts among prisoners in penal institutions is more like an articulated system of introduction to homosexual experience than is homosexual development in the free community. The third type of deviant sexual acts to be considered are those most specifically prosecuted by law-enforcement agencies; they involve aggression, youth, close kin relations, and public disturbance a typology suggested both in Wheeler and in Indiana University ; see pp. Most of these acts are committed by individuals whose behavior is the result of needs developed outside any subcultural or deviant training ground composed of other persons oriented toward the same behavior. The origins of heterosexual pedophilia, for example, seem to lie in the incapacity of the male to establish any meaningful relationship with an adult female or in many cases a failure to find any sociosexual outlet at any level of psychological involvement. The pedophile resorts to children because the difference in age gives him a sense of power over them as well as the hope that he will meet with an uncritical reception. There is no social support for the act either before or after its occurrence. The individual has the latent capacity to commit the act without any social support, and at the intersection of the appropriate forces aging, alcohol, fatigue, emotional stress a sexual contact with a child occurs. The model of the behavior that seems to be most useful is that of the releasing mechanism. The pedophile has learned in childhood a certain set of responses that gives him the potential for the act as an adult. Under the appropriate circumstances the potential is realized. Other sexual acts of the third type that have some of the aspects of pedophilia are homosexual pedophilia, exhibitionism, compulsive peeping, and sex offenses involving incest and the use of force. In the cases of peeping, assaultive offenses, and incest there are certain complicating social or cultural factors. Peeping and the use of minimal aggression in sexual relations are not necessarily viewed as abnormal or deviant. The act of peeping is something that many males have performed when confronted by a lighted unshaded window; however, for the impulse to invade and dominate the sexual life of the individual to such an extent that he must seek out windows in which to look suggests that more than a simple heterosexual interest is involved. A certain amount of aggression by males is expected in the process of sexual exploration in Western culture, and it is clear that excessive force is used more frequently than is reported to the agencies of law enforcement. There are indications that those college-level males who do use force have certain other characteristics that differentiate them from males who do not use force. The aggressive male is commonly responding to his own needs rather than to the interactional situation in which he is involved. The problem of sexual contact between relatives is confined primarily to father-daughter contacts and to a lesser extent to those between brothers and sisters and between cousins. The last two are usually transitory childhood contacts or those that take place just after puberty, and in the case of brother-sister incest they may be made more complicated by the presence of mental deficiency. Father-daughter contacts are most prevalent in rural, or rural-origin, families. The families in which such contacts occur commonly are extremely disorganized families in which the father converts the daughter into a source of sexual and often pseudo-marital relations Kaufman et al. With very young daughters the offense often has elements of pedophilia. A useful point to be made about deviant behavior of this third type is that over long periods of time it represents a relatively stable proportion of all offenses known to the police, of all persons arrested, and of all felons in penal institutions. In addition, the rates per hundred thousand in the population have remained stable for many years. The stability of these rates indicates that disturbed and disorganized families represent a rather constant source of individuals who grow up with strategic weaknesses in their character structures and thus become sexual of fenders. The rate of increase in the number of such persons, however, does not exceed the growth rate of the population, indicating that the roots of these kinds of deviant acts are in the family, as the basic unit of social organization, rather than in secondary social structures. As can be seen from the foregoing discussion, the forms of sexual behavior that are approved arise from sources very similar to those from which the forms called deviant arise, and the margins between one and the other are sharp in moral evaluation but vague in fact. For the vast majority of deviant sexual acts, negative sanctions are frequently expressed but only sporadically enforced. For a smaller proportion of acts, deviant behavior involves recognizable social organization that serves either as a learning structure or as a performance structure for the development and maintenance of the behavior. Finally, for a very small proportion there seem to be no social structural components to the behavior, either for its development or for its continuation, and its origins seem most likely to be in early familial life, as was explained above. With the general absence of mediating social structures between the original development of sexual capacity in childhood and the performance of sexual roles in adulthood the conditions described above are not surprising. Sexual roles are worked out on an individual basis with a general incapacity to share and reformulate very large portions of the sexual experience. Additionally, different religious and political movements have tried to influence or control changes in sexual practices including courting and marriage, though in most countries changes occur at a slow rate. Homosexuality is the romantic or sexual attraction to the same sex. People with a homosexual orientation can express their sexuality in a variety of ways, and may or may not express it in their behaviors. It is possible for a person whose sexual identity is mainly heterosexual to engage in sexual acts with people of the same sex. For example, mutual masturbation in the context of what may be considered normal heterosexual teen development. Gay and lesbian people who pretend to be heterosexual are often referred to as being closeted hiding their sexuality in "the closet". Making that orientation public can be called " coming out of the closet " in the case of voluntary disclosure or " outing " in the case of disclosure by others against the subject's wishes or without their knowledge. Among some communities called "men on the DL" or " down-low " , same-sex sexual behavior is sometimes viewed as solely for physical pleasure. Men who have sex with men , as well as women who have sex with women , or men on the "down-low" may engage in sex acts with members of the same sex while continuing sexual and romantic relationships with the opposite sex. People who engage exclusively in same-sex sexual practices may not identify themselves as gay or lesbian. In sex-segregated environments, individuals may seek relationships with others of their own gender known as situational homosexuality. In other cases, some people may experiment or explore their sexuality with same or different sex sexual activity before defining their sexual identity. People who have a romantic or sexual attraction to both sexes are referred to as bisexual. Pansexuality also referred to as omnisexuality [41] may or may not be subsumed under bisexuality, with some sources stating that bisexuality encompasses sexual or romantic attraction to all gender identities. Alex Comfort and others propose three potential social aspects of sexual intercourse in humans, which are not mutually exclusive: For example: A fertile couple may have intercourse while using contraception to experience sexual pleasure recreational and also as a means of emotional intimacy relational , thus deepening their bonding, making their relationship more stable and more capable of sustaining children in the future deferred reproductive. This same couple may emphasize different aspects of intercourse on different occasions, being playful during one episode of intercourse recreational , experiencing deep emotional connection on another occasion relational , and later, after discontinuing contraception, seeking to achieve pregnancy reproductive, or more likely reproductive and relational. Most world religions have sought to address the moral issues that arise from people's sexuality in society and in human interactions. Each major religion has developed moral codes covering issues of sexuality, morality, ethics etc. Though these moral codes do not address issues of sexuality directly, they seek to regulate the situations which can give rise to sexual interest and to influence people's sexual activities and practices. However, the effect of religious teaching has at times been limited. For example, though most religions disapprove of extramarital sexual relations , it has always been widely practiced. Nevertheless, these religious codes have always had a strong influence on peoples' attitudes to issues of modesty in dress, behavior, speech etc. On the other hand, some people adopt the view that pleasure is its own justification for sexual activity. Hedonism is a school of thought which argues that pleasure is the only intrinsic good. Human sexual activity, like many other kinds of activity engaged in by humans, is generally influenced by social rules that are culturally specific and vary widely. These social rules are referred to as sexual morality what can and can not be done by society's rules and sexual norms what is and is not expected. Some activities, known as sex crimes in some locations, are illegal in some jurisdictions, including those conducted between or among consenting and competent adults examples include sodomy law and adult-adult incest. Some people who are in a relationship but want to hide polygamous activity possibly of opposite sexual orientation from their partner, may solicit consensual sexual activity with others through personal contacts, online chat rooms , or, advertising in select media. Swinging , on the other hand, involves singles or partners in a committed relationship engaging in sexual activities with others as a recreational or social activity. Some people engage in various sexual activities as a business transaction. When this involves having sex with, or performing certain actual sexual acts for another person in exchange for money or something of value, it is called prostitution. Other aspects of the adult industry include phone sex operators, strip clubs , and pornography. Social gender roles can influence sexual behavior as well as the reaction of individuals and communities to certain incidents; the World Health Organization states that, "Sexual violence is also more likely to occur where beliefs in male sexual entitlement are strong, where gender roles are more rigid, and in countries experiencing high rates of other types of violence. The relation between gender equality and sexual expression is recognized, and promotion of equity between men and women is crucial for attaining sexual and reproductive health , as stated by the UN International Conference on Population and Development Program of Action: BDSM is a variety of erotic practices or roleplaying involving bondage , dominance and submission , sadomasochism , and other interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves as practicing BDSM, inclusion in the BDSM community or subculture is usually dependent on self-identification and shared experience. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers , extreme body modification enthusiasts, animal players , latex or rubber aficionados , and others. Bondage includes the restraint of the body or mind. A submissive is someone who gives up the control to a person who wishes to take control. Masochism means an individual who takes pleasure from their own pain or humiliation. Participants who exert sexual dominance over their partners are known as dominants or tops , while participants who take the passive, receiving, or obedient role are known as submissives or bottoms. Individuals are also sometimes abbreviated when referred to in writing, so a dominant person may be referred to as a "dom" for a man or a woman. Sometimes a woman may choose to use the female specific term "Domme". Both terms are pronounced the same when spoken. The precise definition of roles and self-identification is a common subject of debate within the community. In a study, the researchers state that BDSM is a sexual act where they play role games, use restraint, use power exchange, use suppression and pain is sometimes involved depending on individual s. According to the findings, one who participates in BDSM may have greater strength socially and mentally as well as greater independence than those who do not practice BDSM. Before any sexual act occurs, the partners must discuss their agreement of their relationship. They discuss how long the play will last, the intensity, their actions, what each participant needs or desires. The sexual acts are all recorded as consensual and pleasurable to both parties. In a study, interviewed BDSM participants have mentioned that the activities have helped to create higher levels of connection, intimacy, trust and communication between partners. The participants have remarked that they enjoy pleasing their partner in any way they can and many surveyed have felt that this is one of the best things about BDSM. It gives a submissive pleasure to do things in general for their dominant. Where a Dominant enjoys making their encounters all about the submissive. They enjoy doing things that makes their submissive happy. The findings indicate that the surveyed submissives and dominants found BDSM play more pleasurable and fun. The participants have also mentioned improvements in their personal growth, romantic relationships, sense of community and self, the dominant's confidence, and their coping with everyday things by giving them a psychological release. There are many laws and social customs which prohibit, or in some way affect sexual activities. These laws and customs vary from country to country, and have varied over time. They cover, for example, a prohibition to non-consensual sex, to sex outside marriage, to sexual activity in public, besides many others. Many of these restrictions are non-controversial, but some have been the subject of public debate. Most societies consider it a serious crime to force someone to engage in sexual acts or to engage in sexual activity with someone who does not consent. This is called sexual assault , and if sexual penetration occurs it is called rape, the most serious kind of sexual assault. The details of this distinction may vary among different legal jurisdictions. Also, what constitutes effective consent in sexual matters varies from culture to culture and is frequently debated. Laws regulating the minimum age at which a person can consent to have sex age of consent are frequently the subject of debate, as is adolescent sexual behavior in general. Some societies have forced marriage, where consent may not be required. Many locales have laws that limit or prohibit same-sex sexual activity. In the West, sex before marriage is not illegal [ example needed ]. There are social taboos and many religions condemn pre-marital sex. Those found guilty, especially women, may be forced to wed the sexual partner, publicly beaten, or stoned to death. Other studies have analyzed the changing attitudes about sex that American adolescents have outside marriage. Adolescents were asked how they felt about oral and vaginal sex in relation to their health, social, and emotional well-being. Overall, teenagers felt that oral sex was viewed as more socially positive amongst their demographic. The laws of each jurisdiction set the minimum age at which a young person is allowed to engage in sexual activity. In many jurisdictions, age of consent is a person's mental or functional age. Age of consent may vary by the type of sexual act, the sex of the actors, or other restrictions such as abuse of a position of trust. Some jurisdictions also make allowances for young people engaged in sexual acts with each other. Most jurisdictions prohibit sexual activity between certain close relatives. These laws vary to some extent; such acts are called incestuous. Non-consensual sexual activity or subjecting an unwilling person to witnessing a sexual activity are forms of sexual abuse , as well as in many countries certain non-consensual paraphilias such as frotteurism , telephone scatophilia indecent phonecalls , and non-consensual exhibitionism and voyeurism known as " indecent exposure " and " peeping tom " respectively. People sometimes exchange sex for money or access to other resources. Work takes place under many varied circumstances. The person who receives payment for sexual services is called a prostitute and the person who receives such services is known by a multitude of terms, including and most commonly "john. The legal status of prostitution varies from country to country , from being a punishable crime to a regulated profession. Survival sex is a form of prostitution engaged in by people in need, usually when homeless or otherwise disadvantaged people trade sex for food, a place to sleep, or other basic needs , or for drugs.

Archived from the original on 6 December The Kinsey Institute has continued as a research site of important psychological studies for decades. At the time, the Kinsey reports were quite sensational. Never before had the American public seen its private sexual behavior become the focus of scientific scrutiny on such a large scale. The books, which were filled with statistics and scientific lingo, sold remarkably well to the general public, and people began to engage in open conversations about human sexuality. In fact, these books were banned in some countries. Ultimately, the controversy resulted in Kinsey losing funding that he had secured from the Rockefeller Foundation to continue his research efforts Bancroft, Kinsey described a remarkably diverse range of sexual behaviors and experiences reported by the volunteers participating in his research. Behaviors that had once been considered exceedingly rare or problematic were demonstrated to be much more common and innocuous than previously imagined Bancroft, ; Bullough, In , William Masters and Virginia Johnson published a book detailing the results of their observations of nearly people who agreed to participate in their study of physiological responses during sexual behavior. Unlike Kinsey, who used personal interviews and surveys to collect data, Masters and Johnson observed people having intercourse in a variety of positions, and they observed people masturbating, manually or with the aid of a device. While this was occurring, researchers recorded measurements of physiological variables, such as blood pressure and respiration rate, as well as measurements of sexual arousal, such as vaginal lubrication and penile tumescence swelling associated with an erection. In total, Masters and Johnson observed nearly 10, sexual acts as a part of their research Hock, Based on these observations, Masters and Johnson divided the sexual response cycle into four phases that are fairly similar in men and women: The excitement phase is the arousal phase of the sexual response cycle, and it is marked by erection of the penis or clitoris and lubrication and expansion of the vaginal canal. During plateau , women experience further swelling of the vagina and increased blood flow to the labia minora, and men experience full erection and often exhibit pre-ejaculatory fluid. Both men and women experience increases in muscle tone during this time. Orgasm is marked in women by rhythmic contractions of the pelvis and uterus along with increased muscle tension. In men, pelvic contractions are accompanied by a buildup of seminal fluid near the urethra that is ultimately forced out by contractions of genital muscles, i. Resolution is the relatively rapid return to an unaroused state accompanied by a decrease in blood pressure and muscular relaxation. While many women can quickly repeat the sexual response cycle, men must pass through a longer refractory period as part of resolution. The refractory period is a period of time that follows an orgasm during which an individual is incapable of experiencing another orgasm. In men, the duration of the refractory period can vary dramatically from individual to individual with some refractory periods as short as several minutes and others as long as a day. As men age, their refractory periods tend to span longer periods of time. Figure 4. This graph illustrates the different phases of the sexual response cycle as described by Masters and Johnson. Furthermore, they determined that the vagina is a very elastic structure that can conform to penises of various sizes Hock, Figure 5. Till Krech. Issues of sexual orientation have long fascinated scientists interested in determining what causes one individual to be heterosexual while another is homosexual. For many years, people believed that these differences arose because of different socialization and familial experiences. Genetic and biological mechanisms have also been proposed, and the balance of research evidence suggests that sexual orientation has an underlying biological component. In aggregate, the data suggest that to a significant extent, sexual orientations are something with which we are born. Regardless of how sexual orientation is determined, research has made clear that sexual orientation is not a choice, but rather it is a relatively stable characteristic of a person that cannot be changed. Claims of successful gay conversion therapy have received wide criticism from the research community due to significant concerns with research design, recruitment of experimental participants, and interpretation of data. Man can, and sometimes does, engage in relations that the more constitutionally directed animals would refuse. Man may disregard species parity and practice bestiality, disregard secondary sexual disparity and practice homosexuality, and disregard psychic complementarity and establish neurotic sex relations. On the other hand, man may refuse relations because of sexual style, the status of the partner, or the beauty of the partner—a parity irrelevant to the animal. For man, the power of the social over biological determinants extends to the very definition of gender. Money et al. Rules for recruitment to coital relations in general parallel, but do not completely overlap with, those governing marital recruitment. Laws of exogamy define the inner social limits for recruitment of a marital partner. These are extensions of the incest taboo, which is a nearly universal taboo, with exceptions only in such cases as the Egyptian royal family, where brother-sister marriage was permitted, or among Azande nobles, where father-daughter marriage has been permitted. Laws of endogamy define the outer social limits. In human relations, however, endogamy controls potentially fertile relations within the same species. A number of individuals are virtually precluded from recruitment to eroticized heterosexual roles. This is the case with institutionalized populations in prisons or mental hospitals. Likewise, occupational conditions may separate individuals from the opposite sex. Hobos, being homeless, have less access to women, and thus they tend to frequent the lowest status prostitutes and to practice homosexuality. Social control of eroticized role recruitment contributes to the maintenance of the social structure; if society lacked such controls, random mating could disrupt the familial and economic lines of stratification of a society. Moreover, social control of recruitment may enable one social group to dominate another through its power to allocate sexual occasions and facilities. It may also be an internally integrative device, as it is among celibate monastics. According to Ross , such control is necessary to manage a smoldering antagonism that exists between the sexes as groups. Communication employed for recruitment to the eroticized role parallels the communication of arousal in the sex act. Token arousal announces sexual availability. Erotic communication relies heavily on movement, such as the inviting movements of the dance and the arousing tactile movements during coitus. Odors founded in the natural capryl odors and supplemented at the human level by perfumes act upon the deeper levels of consciousness Bloch Cosmetic means of communicating sexual interest include painting and tattooing as well as sexual mutilation. Socially stylized ceremonies of fertility or initiation may announce availability and effect arousal. A few rites, such as subincision, announce sexual availability but reduce sexual enjoyment or arousal potential for the subject Allen ; Westermarck Verbal communication supplements sensory communication in sexual behavior. Speech is so closely identified with sexuality that in some cultures it is forbidden or restricted between persons who are socially precluded from engaging in sexual relations Baker The more intimate a sexual matter, the less the likelihood of communication about it to nonerotic role partners. In many societies, socially structured mores about erotic communication bar young people from arousal and consummatory opportunities. Sexual norms may be learned inferentially by the young or by new social groups, such as immigrants, by observation of behaviors lacking primary erotic meaning, such as forms of dress and of association between the sexes Klausner Classified newspaper advertising and a specialized journalism directed to erotica have long been used for the recruitment of both heterosexual and homosexual partners. Deviant subgroups develop private signaling systems to cue a potential partner without revealing themselves to noninitiate spectators. For example, homosexuals may wear peculiar clothing the definition of which changes from time to time , intersperse their speech with a special argot, or perform certain gestures. They may position themselves to receive such signals by frequenting known haunts. Society not only exerts control over the recruitment of role partners but also attempts to control the types of sexual behaviors enacted and the occasions for their enactment. A quasi-formal control mechanism is exemplified among the Mondurucu by the gang rape to force a recalcitrant female to submit to male authority Murphy Norms also define those behaviors to which it is legitimate to recruit. Early studies of sexual behavior treated cross-cultural comparisons descriptively, presenting various behaviors, sexual art, and technical devices as curiosities Moll ; Krafft-Ebing ; Bloch Correlations between sexual behavior and the overarching cultural ethos allow inference about the types of sexual behaviors to which recruitment is approved in various cultural situations; that is, recruitment norms vary with the ethos. In matristic periods, dominated by a mother religion and exemplified by England after the first millennium, people have a horror of incest and are permissive regarding sex. Social control may be exerted by concrete organizational arrangements. The Nazis, while promoting a policy of sexual abstinence, provided youth camps in which sexual relations took place. Monasteries may debar their inmates from sexual opportunities. Child marriage commits the relationship before the erotic drive appears. The sexes may be physically and, therefore, socially isolated, as in a harem or school. Chaperonage is a way of supervising the young during their meetings. Systems of peer group pressures, such as those exerted by campus sororities or fraternities, encourage socially approved love relationships by subjecting them to ratings by age mates. These controls are more stringent among the upper classes, who have more to lose by a breakdown in the stratification system Goode Legal control takes the form of laws against homosexuality, adultery, sodomy, or pederasty—that is, against behaviors that violate rules governing recruitment to the eroticized role. In England, the Wolfenden Committee on homosexual offenses and prostitution gathered intelligence about sexual behavior from social scientists and psychiatrists as a basis for legislating on sexual recruitment. They concluded that it is the duty of the law not to concern itself with immorality as such but to confine itself to activities that offend against public order and decency. Thus, they recommended that homosexual relationships between adults by mutual consent and in privacy should not fall within the province of criminal law Great Britain. Throughout Anglo-American history, the methods of legal control of sex expression have varied much more than has the accepted doctrine of sexual morality May ; Mueller Sex education is a form of noncoercive, though formal, control. The medical profession in its efforts to control venereal disease, as well as religious groups in their efforts to maintain their own sexual norms, have been instrumental in founding organizations such as the American Society of Sanitary and Moral Prophylaxis in and the American Social Hygiene Association in , now the American Social Health Association. This latter association uses education to combat venereal disease, commercialized prostitution, and other conditions associated with sex delinquency among young people. Protest against efforts to enforce prevailing sexual mores and to control recruitment to the eroticized role is expressed in individual sexual deviance, the formation of groups of individuals with special sexual needs, and movements to change the prevailing mores. The sex offender uses illegitimate means, such as violence or disregard for the consent of the partner, to recruit to coital or noncoital sexual behaviors, or he recruits without regard to rules defining permitted sexual partners. Generally, these individuals are undersexed rather than oversexed. Freudian theory suggests that some sex offenders may be compensating for feelings of bodily damage or phallic inadequacy, or suffering from castration anxiety Hammer Most sex offenders are of average intelligence. Those arrested for incest, however, tend to be older men of subnormal intelligence and antisocial personalities. Apprehended distributors of obscene literature tend to be older, sexually inhibited men of average intelligence who are not hostile. Women are rarely arrested for sexual offenses in American society, except for violating norms regarding public solicitation. The role relations in primarily nonsexual delinquent groups may become eroticized, involving, for instance, group masturbation. Organizations of individuals whose physical status makes it difficult for them to recruit or be recruited to an eroticized role, such as dwarfs or the blind, may oppose prevailing sexual mores, as may those who, though not necessarily handicapped or abnormal in a clinical sense, have sexual requirements that are contrary to the norms. These groups provide evaluational support, facilitate recruitment to the role, and insulate members against the sexual mores of the larger society Hooker Social movements concerned with sex have sought revision of sexual standards, of the laws supporting them, and of the means of enforcing them. Corruption in systems of police regulation of prostitution led to the formation of the International Federation for the Abolition of State Regulation of Vice in It attempted to abolish antisexual taboos, establish a philosophical basis for sexual freedom, and provide education in the form of lectures and clinical advice. The institute was closed by the Nazis, and the world movement collapsed a few years later. The nonerotic components in an eroticized role may link it with a pattern of roles constituting an institution. Historically, eroticized roles have been part of the fabric of economic, political, religious, familial, and other institutions. At certain times, a particular institution, such as the church in Christian society, may exclude the erotic component from its roles and influence its place in the roles of another institution, especially the family. The eroticized role is universally legitimated in the family, and in modern Western society it is legitimated only in the family. However, actual behavior is at variance with this official standard. In the Kinsey samples, 50 per cent of the females and 85 per cent of the males with a high school education reported that they had experienced premarital coitus. Moreover, by the age of forty nearly 26 per cent of the females and 50 per cent of the males had engaged in extramarital coitus. Increasing opportunities for premarital and extramarital coitus accompany the greater mixing of the sexes in the educational, occupational, and social worlds. Legal control of premarital intercourse in American society is generally enforced more strictly in the case of younger participants. Adultery is grounds for divorce in all states. To the extent that coitus takes place outside of marriage the procreative aspect declines in significance. For example, Malinowski thought that the Trobriand Islanders, who have very permissive sexual mores, did not appreciate the connection between coitus and pregnancy, although it is more likely that, while aware of the connection, they were not much interested in it. Discussions of contraception reveal some tensions aroused concerning nonprocreative coital meanings, since contraceptives are not simply designed to prevent conception but to do so while coitus continues. Sexual behavior has been interwoven with religion from earliest times. Furthermore, sexual energy itself may play a role in religious worship. Scott concluded that phallic worship originated in the pleasure associated with coitus and not in any clearly conceived notion that intercourse would produce children. Sex as worshipful, expressive communication with a supraindividual force is illustrated by the activities of temple prostitutes in Babylon. Krafft-Ebing argued that religion and sex could replace one another, since both display a similar scope and quality of excitement at their peaks and both can degenerate under pathological conditions into cruelty. Religious mystical roles may contain an erotic compound in both the Western and Eastern traditions. On the other hand, the cases of the sacerdotal celibate, the religious hermit, or the penitent abstainer illustrate religious exclusion of the sexual component. Religious considerations affect recruitment to eroticized roles in other institutions. Thus, rules of exogamy and endogamy are generally supported by religious sanctions. Religious sanctification of marriage or the withholding of that sanctification affects the recruitment of coital partners. Moreover, religion may contribute to the isolation of the sexes by separating them in worship and by excluding women from sacred precincts. Religious devotion is negatively associated with participation in nonreligious eroticized roles in the United States. The frequencies for all sexual outlets, except for marital coitus, decrease with increasing devoutness Kinsey et al. This association seems to hold in France as well Institut Francais. The relation of sexual behavior to the nature of the state and politics has long been of popular concern. The literature on court ladies and on espionage has described the impact of eroticized roles upon political roles. Sorokin asserted that sexual overindulgence debilitates the entire society. Krafft-Ebing saw a two-directional relation, in which, on the one hand, sexual excess undermines the props of society and, on the other hand, the collapse of society produces sexual aberrations. Utopian schemes have included recommendations for control of eroticized roles. Unwin proposed that, in his new society, Hopousia, there be two kinds of marriage: The acquisition of political power by men usually implies an access to more women. For example, in Bedouin society, a tribal chief is more likely to be polygamous and to retain concubines than is a less powerful member of the tribe. In Europe, royalty as well as the economically powerful have been able to keep mistresses. Sex has a place in the economy both as a marketable commodity and as a component affecting the marketability of nonsexual commodities. Thus economic value can be derived from sexual value. For example, prostitution involves an economic-sexual exchange of this character; the economic exchange ramifies beyond the prostitute and her client to include the pimp who recruits the client, the madam who supplies facilities for the act, and, perhaps, the police who protect all of them from the law. In the case of marriage, the economic-sexual exchange is embedded in a wider set of family and community relations. Sexual role performance consumes facilities, goods, and services, and thus industries emerge around the provision of facilities for recruitment to the eroticized role and for enactment of that role. These range from the provision of meeting places, such as dance halls; the publishing of pornographic, scientific, artistic, and guidance manuals; the supply of pharmaceutical and mechanical contraceptives; and the letting of places, such as a motel room or brothel, for consummating the sex act. Sexual value may be derivative from economic value as well. For example, sexual jealousy, rather than being an innate emotion, may be related to views of women as property. Jealousy is then an anger aroused when property rights are violated. He reasoned that since psychic structure is created by social structure and the core of psychic structure is the sexual function, sexual function is controlled by social structure. These relations affect sexual needs, among others. They also influence concepts of life, morals, and philosophy—that is, ideology—and so influence sex norms. The dominant political minority imposes its ideology in general, and its sexual ideology in particular, on a population. According to this view, the subordinate population thus has sex needs derived from its own class position while being subject to the sexual ideology of another class. Methods of social and psychological research developed in other areas have been used to ascertain frequencies of sexual behaviors as well as social and individual meanings associated with that behavior. Protecting the anonymity of the respondent and establishing the scientific legitimacy of the interviewer are salient bases for rapport during an interview. To maximize the validity of responses, the interviewer must avoid making the respondent feel guilt, anxiety, or defensiveness. Direct questions should be asked with no defensiveness or apology on the part of the interviewer, and terminology should be adapted to the social-class level of the respondent. The inquiry should begin with matters that do not provoke anxiety, such as age, and then proceed to items which are sexual but for which the individual does not feel responsible; thus the interviewer would ask about spontaneous orgasms before asking about masturbation. The fact that anxiety associated with each type of behavior differs among culture or class groups and between the sexes affects the ordering of the questions. For example, homosexuality is less frightening than masturbation for females in American society, while the reverse is true for males; thus, in interviewing females, questions on homosexuality precede those on masturbation, and the reverse order is used for males. As a practical procedure one might request the age at first orgasm, then ask for its source and, if this is not too anxiety-provoking, trace this source through the years. By asking when he first experienced each type of behavior, the burden of denial is placed upon the interviewee. Kinsey correlated the frequencies of each source of outlet—masturbation; premarital, extramarital, and marital coitus; homosexuality; and animal contacts—with demographic factors such as national origin, marital status, age, education, occupational class, rural or urban residence, religious affiliation, and religious devoutness, among others. Intrapsychic meanings of sexual behavior have been studied by correlating projective test responses with the frequencies of behaviors. Observational methods supply data on systems of communication and interaction that are necessary for an analysis of the social organization of sexuality A. The Human Relations Area Files, containing field reports on many societies, have been used to exploit the advantages of both field observation and correlation methods Murdock Ellis The fact that the various sexual behaviors may be ordered along dimensions of greater or lesser intimacy or greater or lesser acceptability has been exploited to construct scales. Podell and Perkins , for example, developed a Guttman scale for ordering types of sexual experience, and Ira Reiss developed a refined Guttman scale for a study of standards of sexual permissiveness.

Any sexual activity that involves the introduction of semen into a woman's vagina, such as during sexual intercourse, or even contact of semen with her vulva, may result in a pregnancy. Sexual activity that involves skin-to-skin contact, exposure to an infected person's bodily fluids or mucosal membranes [27] carries the risk of contracting a sexually transmitted infection. People may not be able to detect that their sexual partner has one or more STIs, for example if they are asymptomatic show no symptoms. Both partners may opt be tested for STIs before engaging in sex. Crab lice typically are found attached to hair in the pubic area but sometimes are found on coarse hair elsewhere on the body for example, eyebrows, eyelashes, beard, mustache, chest, armpits, etc. Pubic lice infestations pthiriasis are spread through direct contact with someone who is infested with the louse. Typically, older men and women maintaining interest in sexual interest and activity could be therapeutic; it is a way of expressing their love and care for one another. Factors such as biological and psychological factors, diseases, mental conditions, boredom with the relationship, and widowhood have been found to contribute with the common decrease in sexual interest and activity in old age. National sex surveys given in Finland in the s revealed aging men had a higher incidence of sexual intercourse compared to aging women and that women were more likely to report a lack of sexual desire compared to men. Regression analysis, factors considered important to female sexual activity included: Both genders in the study agreed they needed good health, good sexual functioning, positive sexual self-esteem, and a sexually skilful partner to maintain sexual desire. Heterosexuality is the romantic or sexual attraction to the opposite sex. Heterosexual sexual practices are subject to laws in many places. In some countries, mostly those where religion has a strong influence on social policy , marriage laws serve the purpose of encouraging people to have sex only within marriage. Sodomy laws were seen as discouraging same-sex sexual practices, but may affect opposite-sex sexual practices. Laws also ban adults from committing sexual abuse , committing sexual acts with anyone under an age of consent , performing sexual activities in public, and engaging in sexual activities for money prostitution. Though these laws cover both same-sex and opposite-sex sexual activities, they may differ in regard to punishment, and may be more frequently or exclusively enforced on those who engage in same-sex sexual activities. Different-sex sexual practices may be monogamous , serially monogamous, or polyamorous , and, depending on the definition of sexual practice, abstinent or autoerotic including masturbation. Additionally, different religious and political movements have tried to influence or control changes in sexual practices including courting and marriage, though in most countries changes occur at a slow rate. Homosexuality is the romantic or sexual attraction to the same sex. People with a homosexual orientation can express their sexuality in a variety of ways, and may or may not express it in their behaviors. It is possible for a person whose sexual identity is mainly heterosexual to engage in sexual acts with people of the same sex. For example, mutual masturbation in the context of what may be considered normal heterosexual teen development. Gay and lesbian people who pretend to be heterosexual are often referred to as being closeted hiding their sexuality in "the closet". Making that orientation public can be called " coming out of the closet " in the case of voluntary disclosure or " outing " in the case of disclosure by others against the subject's wishes or without their knowledge. Among some communities called "men on the DL" or " down-low " , same-sex sexual behavior is sometimes viewed as solely for physical pleasure. Men who have sex with men , as well as women who have sex with women , or men on the "down-low" may engage in sex acts with members of the same sex while continuing sexual and romantic relationships with the opposite sex. People who engage exclusively in same-sex sexual practices may not identify themselves as gay or lesbian. In sex-segregated environments, individuals may seek relationships with others of their own gender known as situational homosexuality. In other cases, some people may experiment or explore their sexuality with same or different sex sexual activity before defining their sexual identity. People who have a romantic or sexual attraction to both sexes are referred to as bisexual. Pansexuality also referred to as omnisexuality [41] may or may not be subsumed under bisexuality, with some sources stating that bisexuality encompasses sexual or romantic attraction to all gender identities. Alex Comfort and others propose three potential social aspects of sexual intercourse in humans, which are not mutually exclusive: For example: A fertile couple may have intercourse while using contraception to experience sexual pleasure recreational and also as a means of emotional intimacy relational , thus deepening their bonding, making their relationship more stable and more capable of sustaining children in the future deferred reproductive. This same couple may emphasize different aspects of intercourse on different occasions, being playful during one episode of intercourse recreational , experiencing deep emotional connection on another occasion relational , and later, after discontinuing contraception, seeking to achieve pregnancy reproductive, or more likely reproductive and relational. Most world religions have sought to address the moral issues that arise from people's sexuality in society and in human interactions. Each major religion has developed moral codes covering issues of sexuality, morality, ethics etc. Though these moral codes do not address issues of sexuality directly, they seek to regulate the situations which can give rise to sexual interest and to influence people's sexual activities and practices. However, the effect of religious teaching has at times been limited. For example, though most religions disapprove of extramarital sexual relations , it has always been widely practiced. Nevertheless, these religious codes have always had a strong influence on peoples' attitudes to issues of modesty in dress, behavior, speech etc. On the other hand, some people adopt the view that pleasure is its own justification for sexual activity. Hedonism is a school of thought which argues that pleasure is the only intrinsic good. Human sexual activity, like many other kinds of activity engaged in by humans, is generally influenced by social rules that are culturally specific and vary widely. These social rules are referred to as sexual morality what can and can not be done by society's rules and sexual norms what is and is not expected. Some activities, known as sex crimes in some locations, are illegal in some jurisdictions, including those conducted between or among consenting and competent adults examples include sodomy law and adult-adult incest. Some people who are in a relationship but want to hide polygamous activity possibly of opposite sexual orientation from their partner, may solicit consensual sexual activity with others through personal contacts, online chat rooms , or, advertising in select media. Swinging , on the other hand, involves singles or partners in a committed relationship engaging in sexual activities with others as a recreational or social activity. Some people engage in various sexual activities as a business transaction. When this involves having sex with, or performing certain actual sexual acts for another person in exchange for money or something of value, it is called prostitution. Other aspects of the adult industry include phone sex operators, strip clubs , and pornography. Social gender roles can influence sexual behavior as well as the reaction of individuals and communities to certain incidents; the World Health Organization states that, "Sexual violence is also more likely to occur where beliefs in male sexual entitlement are strong, where gender roles are more rigid, and in countries experiencing high rates of other types of violence. The relation between gender equality and sexual expression is recognized, and promotion of equity between men and women is crucial for attaining sexual and reproductive health , as stated by the UN International Conference on Population and Development Program of Action: BDSM is a variety of erotic practices or roleplaying involving bondage , dominance and submission , sadomasochism , and other interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves as practicing BDSM, inclusion in the BDSM community or subculture is usually dependent on self-identification and shared experience. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers , extreme body modification enthusiasts, animal players , latex or rubber aficionados , and others. Bondage includes the restraint of the body or mind. A submissive is someone who gives up the control to a person who wishes to take control. Masochism means an individual who takes pleasure from their own pain or humiliation. Participants who exert sexual dominance over their partners are known as dominants or tops , while participants who take the passive, receiving, or obedient role are known as submissives or bottoms. Individuals are also sometimes abbreviated when referred to in writing, so a dominant person may be referred to as a "dom" for a man or a woman. Sometimes a woman may choose to use the female specific term "Domme". Both terms are pronounced the same when spoken. The precise definition of roles and self-identification is a common subject of debate within the community. In a study, the researchers state that BDSM is a sexual act where they play role games, use restraint, use power exchange, use suppression and pain is sometimes involved depending on individual s. According to the findings, one who participates in BDSM may have greater strength socially and mentally as well as greater independence than those who do not practice BDSM. Before any sexual act occurs, the partners must discuss their agreement of their relationship. They discuss how long the play will last, the intensity, their actions, what each participant needs or desires. The sexual acts are all recorded as consensual and pleasurable to both parties. In a study, interviewed BDSM participants have mentioned that the activities have helped to create higher levels of connection, intimacy, trust and communication between partners. The participants have remarked that they enjoy pleasing their partner in any way they can and many surveyed have felt that this is one of the best things about BDSM. It gives a submissive pleasure to do things in general for their dominant. Where a Dominant enjoys making their encounters all about the submissive. They enjoy doing things that makes their submissive happy. The findings indicate that the surveyed submissives and dominants found BDSM play more pleasurable and fun. The participants have also mentioned improvements in their personal growth, romantic relationships, sense of community and self, the dominant's confidence, and their coping with everyday things by giving them a psychological release. There are many laws and social customs which prohibit, or in some way affect sexual activities. These laws and customs vary from country to country, and have varied over time. They cover, for example, a prohibition to non-consensual sex, to sex outside marriage, to sexual activity in public, besides many others. Many of these restrictions are non-controversial, but some have been the subject of public debate. Most societies consider it a serious crime to force someone to engage in sexual acts or to engage in sexual activity with someone who does not consent. This is called sexual assault , and if sexual penetration occurs it is called rape, the most serious kind of sexual assault. The details of this distinction may vary among different legal jurisdictions. Also, what constitutes effective consent in sexual matters varies from culture to culture and is frequently debated. Laws regulating the minimum age at which a person can consent to have sex age of consent are frequently the subject of debate, as is adolescent sexual behavior in general. Some societies have forced marriage, where consent may not be required. Many locales have laws that limit or prohibit same-sex sexual activity. In the West, sex before marriage is not illegal [ example needed ]. Ellis, Havelock Studies in the Psychology of Sex. Volume 4: Sex in Relation to Society. Random House.

One premise of psychoanalytic doctrine is that the general developmental process of childhood includes psychosexual development. The intrauterine environment may prove hostile mechanically, metabolically, or because of the invasion of foreign organisms, viruses for example. The embryo itself may be its own enemy, as when a particular developmental phase or system fails, with subsequent deleterious effects on another phase or system. For example, if the testes differentiate imperfectly in a genetic male, then the fetal testicular secretions fail, with the result that the anlagen of the external genital morphology develop as either completely or partially female, depending on the degree of testicular failure. Contrarily, in the case of a genetic female, if the fetal adrenal cortex functions erroneously, so as to produce an excess of androgen in the place of expected cortisone, then the anlagen of the external genitalia will masculinize in their development, even to the point that the genital tubercle becomes a fully formed penis instead of a clitoris. Both of the foregoing examples of an error in embryonic sexual development illustrate the principle of the critical period, that is to say, that period in the development of some system or function when the organism passes from a neutral or undifferentiated stage to a differentiated one. It is during this critical period that development is vulnerable to interference and deflection, which, if they occur, will leave a permanent residual in structure or function. The further development of the organism will then in some degree be determined by, or influenced by, the outcome of the critical period. The concept of the critical period applies not only to morphologic and prenatal development, but to behavioral, psychological, and postnatal development as well. In behavioral science, the European animal ethologists were the first to observe that patterns of behavior, including sexual behavior, can be experimentally changed during a critical, developmental learning period, and thenceforth this deviance becomes relatively fixed. In other words, particular atypical experiences may interfere with or deform the genetic, hormonal, or neural norms of behavioral development otherwise expected. The justly famous experiments of Harlow see Money a , chapter 7 on the macaque monkey are a case in point. The experimental monkeys showed that opportunity to play with age-mates in early childhood was a developmental prerequisite to the achievement of normal copulatory ability in adolescence. Depriving the infants of childhood play, combined with depriving them of interaction with their mothers by rearing them with dummy mothers made of wire covered with a piece of towel, had particularly adverse effects. Such doubly deprived animals were unable to adapt to the motions of mating and to effect sexual intercourse even when paired with mates selected for experience and gentleness. Those few females in whom pregnancy was finally achieved were incompetent to mother their own young. They neglected and injured them, sometimes cruelly. Other aspects of their behavior, in general, also appeared to be grossly disordered. Another illustrative experiment is that of Birch Female rats were raised in isolation with a rubber collar or ruff around their necks, which deprived them of the experience of licking themselves or others. They were finally released from their collars to deliver their first litter. Instead of licking the young as they were born, they ate most of them. The surviving 5 per cent were retardedly and improperly retrieved and badly suckled; some were eaten after being carried to the nest. Three survivors of a large litter died of starvation. Their mother had shepherded them under her chin every time they approached her belly to search for a nipple. Experiments in population density with rats have demonstrated yet another way in which behavioral experience, namely crowding, may induce aberrant sexual and social behavior Calhoun , affecting even the unborn fetuses and their future behavior, presumably via the maternal endocrine system Keeley The proper understanding of psychosexual development and of erroneous development in human beings requires focusing attention on experience, behavior, and social interaction during the formative years of childhood. In man, perhaps even more so than in lower species, peculiarities and special features of experience during critical periods may change the expected genetic, hormonal, or neural norms of development. Human hermaphroditism, for which there are several different etiologies, is conventionally defined in terms of a discrepancy between the gonads ovaries, testes, or, rarely, ovotestes and the morphology of the external genitalia. Sometimes the discrepancy may be total, as indicated at the beginning of this article, namely, when the gonads are testicular and the external organs are perfectly female the syndrome of testicular feminization or when the external organs are perfectly male except for an empty scrotum, the gonads being ovaries and in proper ovarian position a rare variant of the hyperadrenocortical syndrome of female hermaphroditism. Most commonly in hermaphroditism, however, the discrepancy between gonads and external organs is incomplete, by reason of the fact that the external organs are themselves imperfectly differentiated as either male or female. In this incompleted state of differentiation, the external sex organs of either sex look remarkably similar: Because confusion is possible and because medical decisions may sometimes differ, it may so happen that two individuals of identical genetic, gonadal, and hormonal diagnosis are assigned to different sexes. The expected outcome of such sex assignment is that psychosexual differentiation will proceed to take place congruously with assignment and rearing. Ideally, the external organs will have been repaired surgically as early as possible, so as to conform to the assigned sex. Even with delayed genital repair, it has proved possible for psychosexual differentiation to take place in keeping with assigned sex when genetic, gonadal, and hormonal sex are at variance. Ideally, for psychosexual differentiation to be brought to maturity at puberty, assigned sex should not be at variance with hormonal sex and the secondary sexual changes of the body that are hormonally controlled. This ideal can be met in modern endocrinology. Yet, there are occasional untreated cases; among them are cases of hormonal virilization in girls with the hyperadrenocortical syndrome, which is remarkable in view of the intensity of virilization and its early onset before the usual age of puberty. These cases show that the persistence of a feminine psychosexual differentiation is possible despite the hormonal contradiction and its severe handicap to proper adolescent social maturation. In psychosexual differentiation, the crucial variables, which may in hermaphroditism be independent of one another and may be overridden by the experiential effects of assignment and rearing, are five: Psychosexual differentiation itself transcends not only all five of these variables but also the assigned sex in the syndrome of transvestism with transsexualism, which has, therefore, been treated, and not without reasonable success, by surgical, hormonal, and social sex reassignment Benjamin ; Pauly To have found rare clinical cases in which the five physical variables can be overridden is not, of course, to have proved that the physical variables do not under other circumstances contribute to, or help determine, psychosexual differentiation. What has been proved is not that psychosexual differentiation is always and exclusively a matter of behavioral and experiential life history but that experiences determined by rearing are far more potent than might otherwise have been expected. Harlow observed that the young male monkeys made more threats toward other monkeys, both male and female, than did the young females. The young females retreated more often than the males, specifically by adopting the female sexual posture. The young males initiated more play contacts, with playmates of either sex, than did the females; and the males had a monopoly on rough-and-tumble play. With increasing age, the males showed increasing frequency of the male mounting position in their copulatory play. They showed little grooming behavior, which, in adults, is more a characteristic of female than male sexual behavior. Systematic experimental attempts to study the development of masculinity and femininity have confined themselves to the secondary data of questionnaires or interviews or to the oblique data of free association, projective tests, and play. Although not thoroughly consistent or definitive, the findings show that psychosexual differentiation varies with age and in some degree is related to family and class differences in child-rearing practices and the emotional quality of the relationship between the child and each parent. It is not difficult for a child under a year of age to adjust to a sex reassignment, provided the parents can also adjust. But the older the child—for example, if he is past the age of learning to talk and is becoming acquainted with the verbal and other signals of gender difference—and the further that psychosexual differentiation has progressed without ambiguity, the progressively less likely it is that an imposed sex reassignment will be successfully assimilated. It thus appears that the establishment of a psychosexual identity and gender role roughly parallels the learning of the native language. The critical period, in which the basic essentials are laid down, is ended probably by the kindergarten age. The remaining years of childhood are years of consolidation until the hormonal changes of adolescence bring psychosexual differentiation to its completed expression in both the subjective and the behavioral aspects of falling in love, courtship, mating, and parenthood. Hormonal puberty is temporarily delayed sometimes, and sometimes it never occurs, except for the intervention of hormonal replacement therapy. Without the advent of hormonal puberty, psychosexual differentiation remains to some degree in a state of infantilism. A few hormonally prepubertal teen-agers are able to overcome the handicap of a sexually unappealing, prepubertal body morphology and to keep up socially with their age-mates. But the task is difficult and the competition harsh, so that the majority lag in social maturation. They retreat, as it were, to a younger age group, waiting for the day when their bodies no longer tell a lie about their ages. If this waiting is too protracted, there may be a permanent scar in social development. But their achievement is, in fact, a simulation, insofar as their proprioceptive erotic sensations and cognitional eroticism in general are not the same as they will be after hormonal treatment has begun. A male, for example, whatever peak of erotic experience he may reach, does not have an orgasm as he will later experience it. He does not have sex dreams incorporating orgasm, wet or dry; he does not have masturbation imagery, or much of an urge to masturbate; and he does not respond with the same frequency or intensity to erotic perceptual stimuli, visual and narrative, as he will after hormonal puberty is induced. Probably he is incapable of experiencing an episode of that very intense concatenation of feeling so little attended to scientifically—namely, falling in love. Failure to develop full normal maturity of psychosexual differentiation after hormonal puberty, natural or induced, may represent one of four types of failure in the growth process, regardless of etiology. One is a simple arrestment of development that had been otherwise normal up to that point. The second is a regression from a once more advanced level. The third is the introduction of a fault or error in development. The fourth is a continued persistence of developmental error from an earlier period. In psychosexual differentiation, a persistent error may have had its genesis in faulty differentiation at the outset of childhood or perhaps in regression occurring in a later period of childhood. It is probable that a large proportion of psychosexual pathology in evidence at adolescence does not have its initial origins in postpuberty but represents the persistence of faulty psychosexual differentiation earlier. The fault manifests itself in full only under the influence of hormonal maturation. Theories of the life history dynamics of homosexuality have recently been comprehensively reviewed by Pritchard and by Bieber and his associates see Society of Medical Psychoanalysts Whatever the type or timing of developmental error, the responsible or contributing etiologic agent may be, singly or in combination, genetic, gestational, metabolic, nutritional, toxic-infective, traumatic, behavioral-experiential, social-interactional, or otherwise. The cold scientific fact of the matter is that astonishingly little is known of the etiology of psychosexual pathologies. Knowledge of their phenomenology and natural history is greater Money c , although it is far from complete. Current advances are being made in knowledge regarding brain mechanisms mediating sexual behavior. Brain ablation was the earliest experimental technique for such investigation, gains and losses in sexual behavior being related to damaged or removed neural centers and pathways. A newer technique is that of direct electrical stimulation of neural centers and pathways by means of micro-electrodes implanted in the brain. The limbic cortex attaches to the reptilian brain like a pair of headphones covered by the helmet of the neocortex. In the reptilian brain, the centers of the hypothalamus lie in close proximity to the pituitary gland. The hypothalamic-pituitary axis is of fundamental importance in sex, for it is here that the nervous system and the endocrine system meet—here that neural messages become neurohumoral, and neurohumoral ones become hormonal. It is here that the hypothalamus regulates cyclic functioning of the pituitary gonadotropic hormones, which in turn regulate the hormonal functioning of the gonads. Here then, indirectly, lie some of the dictates of behavior related to the effecting of pregnancy and parenthood. The limbic system also collaborates. In the ringlike arrangement of structures on each side of the brain that form the limbic system, there is in the upper forward part the septum and below it the amygdala. MacLean, exploring the representation of sexual function in the limbic system of the squirrel monkey by means of implanted electrodes, found that partial sexual functions could be directly activated by stimulation of the septal area. In the adjacent area of the amygdala chewing and salivation were activated, with partial erection occurring after many seconds of stimulation or as a rebound phenomenon after the termination of stimulation. MacLean conjectured that the topographical representation of the head end and the rear end of the body in such close proximity bears some relationship to the intimate interplay of behavior in the oral and sexual spheres. In lower animals, this interplay is in evidence in sexual smelling and in the delivery of the young. In human beings it appears in ordinary love play. Exaggerated and distorted, it appears also in the pathologies of anal-oral and urethral—oral stimulation and in stimulation from smelling, smearing, or ingesting feces or urine. The proximity of representation of all the phylogenetically primeval action systems and their related nonverbal feeling or emotion in the old brain may help to explain other pathologies of sex, such as the association of sexual stimulation with mutilation and attack in masochism and sadism. Another new direction in the neurophysiology of sex lies in neurohormonal research reviewed by Money b. One approach is to inject a sex hormone into the body and then study its effect on sexual centers in the limbic system and in the hypothalamus and adjacent midbrain nuclei. Olds , p. A second approach in neurohormonal research is to implant hormones directly into sexual centers in and around the hypothalamus. Fisher used the technique of implanting fluid hormone through a microcannula. By introducing minute amounts of testosterone into the preoptic area of male rats, he obtained rather bizarre combinations of mating and maternal behavior, including nest building and persistent retrieving and grooming of foster litters of young. Harris, Michael, and Scott used the improved technique of implanting microamounts of solid hormone and were able to induce a state of sustained sexual receptivity in cats, in the absence of genitopelvic estrus. Michael ; used radioactive estrogen and traced its site of action in the brain by making autoradiographs of the sliced brain. These various implantation neurohormonal experiments have shown that the sex hormones are not clearly sex specific, but often paradoxical in their neurobehavioral effect. Other chemicals may be found capable of producing their effects. The ultimate possible application of this new breakthrough in dealing with psychosexual pathology cannot be foreseen at the present time. A third approach in neurohormonal research is to alter the neural organization of later sexual behavior by injecting hormones into the pregnant mother or newborn animal guinea pig and rat. The findings of several investigators converge, tentatively indicating that, dependent on species differences in gestational age at birth, there is a critical period around the time of birth when androgen has an organizing effect on neural centers in the hypothalamus. Androgen is thus implicated as an active organizer of the sexual control system, both in terms of reproductive cycles and sexual behavior. At a critical period earlier in embryonic life, androgen is an active organizer substance without which the internal anlagen of the female reproductive anatomy persist and the anlagen of the external organs feminize Jost One conjectures a relationship here with the greater vulnerability of the male to disease and death, which would create an unequal sex ratio except for the fact that males are born to females. One conjectures also a connection with the fact that psychosexual disorders have a higher incidence in men than in women, with some of the psycho-sexual anomalies, like fetishism, voyeurism, and exhibitionism, being to all intents and purposes unheard of in females. The higher incidence of psychosexual pathologies in the male may be related to a sex difference in erotic arousal patterns. This difference is manifested in the greater capacity of the male to be aroused erotically and genitopelvically, and to be ready for immediate release, by pictorial and narrative imagery. Such stimuli arouse the female sentimentally to want her lover or husband; but she is dependent on direct tactile stimulation, more than the male, for the arousal of genitopelvic eroticism. There is some evidence in the psychology of hermaphroditism that the male arousal pattern may be neurally organized under the influence of androgen in fetal life. It will be for further research to determine whether the development of psychosexual pathology in the male may be rooted in part in imperfect or faulty neurohormonal organization at this early period. One thing already quite clear in the evidence of hermaphroditism is that a masculine type of arousal pattern is perfectly compatible with entirely feminine cognitive content and imagery of eroticism that parallels the sex of assignment. Perceptual stimulants to sexual arousal and the reproductive cycle vary with the species. The relation between light stimulation and the release of pineal hormones is being newly investigated in the rat. Acuity of the sense of smell in human females Money b is regulated by estrogen and varies with the menstrual cycle. Its relation to other cyclic sexual phenomena or to sexual disorder has not been investigated. Odor may be the agent responsible, in the macaque monkey, for fluctuation in male sexual behavior in rhythm with the female menstrual cycle, as described by Michael and Herbert In addition to benefiting from the new neurophysiological techniques, contemporary sex research has also benefited from the new techniques in genetics. The relevance of the new findings to the theory of psychosexual pathology has been chiefly negative: Affected individuals are phenotypic males with an extra X chromosome. There appears to be an unusually high incidence of psychopathology, including sexual disorders, that develops in association with the syndrome Money a. Otherwise genetics cannot be directly implicated in psychosexual ambiguity Money b. Disorders of sexual psychology express themselves in full in adolescence after the advent of hormonal puberty brings erotic functioning to maturity. It is probable that the majority of such disorders have their initial origins in faulty psychosexual differentiation persisting from early childhood. Later error or regression of differentiation are also possible, as is simple arrestment in psychosexual growth. Faults, errors, regression, and arrest of development have, on the one hand, a chronologic origin and, on the other hand, an etiologic origin. The chronologic origin may fall within a critical period, with resultant immutability or refractoriness to change. The etiologic origin may be single or multiple. An etiologic factor may by itself represent only a potential vulnerability to psychosexual disorder, materializing only when in combination with another factor or factors. Thus a genetic vulnerability may materialize only when the behavioral environment conspires appropriately. Etiologic considerations include genetic, gestational, metabolic, nutritional, toxic-infective, traumatic, behavioral-experiential, and social-interactional factors. Benjamin, H.

Citing research that suggests not only that gay conversion therapy is ineffective, but also potentially harmful, legislative efforts to make such therapy illegal have either been enacted e. Read this draft of Dr. Many people conflate sexual orientation with gender identity because of stereotypical attitudes that exist about homosexuality. In reality, these are two related, but different, issues. Generally, our gender identities correspond to our chromosomal and phenotypic sex, but this is not always the case. When individuals do not feel comfortable identifying with the gender associated with their biological sex, then they experience gender dysphoria. Gender dysphoria is a diagnostic category in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders DSM-5 that describes individuals who do not identify as the gender that most people would assume they are. This dysphoria must persist for at least six months and result in significant distress or dysfunction to meet DSM-5 diagnostic criteria. In order for children to be assigned this diagnostic category, they must verbalize their desire to become the other gender. Approximately 1. Many people who are classified as gender dysphoric seek to live their lives in ways that are consistent with their own gender identity. This involves dressing in opposite-sex clothing and assuming an opposite-sex identity. These individuals may also undertake transgender hormone therapy in an attempt to make their bodies look more like the opposite sex, and in some cases, they elect to have surgeries to alter the appearance of their external genitalia to resemble that of their gender identity Figure 6. Transgender people who attempt to alter their bodies through medical interventions such as surgery and hormonal therapy are called transsexual individuals. Not all transgender individuals choose to alter their bodies: Figure 6. Chaz Bono, a transgender male, is a well-known person who transitioned from female to male. In this brief video , Chaz Bono discusses the difficulties of growing up identifying as male, while living in a female body. Gender is deeply cultural. Like race, it is a social construction with real consequences, particularly for those who do not conform to gender binaries. Although gender has traditionally been considered in binary terms male or female , increasingly gender is being seen as a spectrum; however, our vocabulary is still limited in terms of the ways in which we describe gender identity. Issues related to sexual orientation and gender identity are very much influenced by sociocultural factors. Even the ways in which we define sexual orientation and gender vary from one culture to the next. While in the United States exclusive heterosexuality is viewed as the norm, there are societies that have different attitudes regarding homosexual behavior. In fact, in some instances, periods of exclusively homosexual behavior are socially prescribed as a part of normal development and maturation. There is a two-gendered culture in the United States. We tend to classify an individual as either male or female. However, in some cultures there are additional gender variants resulting in more than two gender categories. For example, in Thailand, you can be male, female, or kathoey. Within a few months, the twins were experiencing urinary problems; doctors recommended the problems could be alleviated by having the boys circumcised. Distraught, Janet and Ronald looked to expert advice on what to do with their baby boy.

As a result of this work, he developed a theory of psychosexual neutrality..

Sexuality may be experienced and expressed in a variety of ways, including thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles, and relationships.

Some researchers believe that sexual behavior is determined by genetics; however, others assert that it is largely molded by the environment. Human sexuality impacts, and is impacted by, cultural, political, legal, and philosophical aspects of life, and can interact with issues of morality, ethics, theology, spirituality, or religion.

Like food, sex is an important part of our lives. From an evolutionary perspective, the reason is obvious—perpetuation of the species. Sexual behavior in humans, however, involves much more than reproduction. This section provides an overview of research that has been conducted on human sexual behavior and motivation.

This section will close with a discussion of issues related Definition of sexual behavior gender and sexual orientation. Much of what we know about the physiological mechanisms that underlie sexual behavior and motivation comes from animal research. Surprisingly, medial preoptic lesions do not change how hard a Definition of sexual behavior rat is willing to work to gain access to a sexually receptive female Figure 1.

This suggests that the ability to engage in sexual Definition of sexual behavior and the motivation to Definition of sexual behavior so may be mediated by neural systems distinct from one another. Figure 1.

A male rat that cannot engage in sexual behavior still seeks receptive females, suggesting that the ability to engage in sexual behavior and the motivation to do so are mediated by different systems in the brain.

Jason Snyder. Animal research suggests that limbic system structures such as the amygdala and Definition of sexual behavior accumbens are especially important for sexual motivation. Damage to these Definition of sexual behavior results in a decreased motivation to engage in sexual behavior, while leaving the ability to do so intact Figure 2 Everett, Figure 2.

The medial preoptic area, an area of the hypothalamus, is involved in the ability to engage in sexual behavior, but it does not affect sexual motivation. In contrast, the amygdala and nucleus accumbens are continue reading in motivation for sexual behavior, but they do not affect the ability to engage in it. Although human sexual behavior is much more complex than that seen in rats, some parallels between Definition of sexual behavior and humans can be drawn from this research.

The worldwide popularity of drugs used to treat erectile dysfunction Conrad, speaks to the fact that sexual motivation and the ability to engage in sexual behavior can also be dissociated in humans. Moreover, disorders that involve abnormal hypothalamic Definition of sexual behavior are often associated with hypogonadism reduced function of the gonads and reduced sexual function e.

Sexual Orientation

For example, many animals show no sign of sexual motivation in the absence of the appropriate combination of sex hormones from their gonads. Physicians were considered authorities on Definition of sexual behavior issues related to sex, despite the fact that they had little to no training in these issues, and it is likely that most of what people knew about sex had been learned either through their own experiences or by talking with their peers.

Convinced that people Definition of sexual behavior benefit from a more open dialogue on issues related to human sexuality, Dr. Alfred Kinsey of Indiana University initiated large-scale survey research on the topic Figure 3. The results of some of these efforts were published in two books— Sexual Behavior in the Human Male and Sexual Behavior in the Human Female —which were published in andrespectively Bullough, Figure 3.

Till Krech. Issues of sexual orientation have long fascinated scientists interested in determining what causes one individual to be heterosexual while another is homosexual. For many years, people believed that these differences arose because of different socialization and familial experiences. Genetic and biological mechanisms have also been proposed, and the balance of research evidence suggests that sexual orientation has an underlying biological component. In aggregate, the data suggest that to a significant extent, sexual orientations are something with which we are born. Regardless of how sexual orientation is determined, research has made clear that sexual orientation is not a choice, but rather it is a relatively stable characteristic of a person that cannot be changed. Claims of successful gay conversion therapy have received wide criticism from the research community due to significant concerns with research design, recruitment of experimental participants, and interpretation of data. As such, there is no credible scientific evidence to suggest that individuals can change their sexual orientation Jenkins, Robert Spitzer, the author of one of the most widely-cited examples of successful conversion therapy, apologized to both the scientific community and the gay community for his mistakes, and he publically recanted his own paper in a public letter addressed to the editor of Archives of Sexual Behavior in the spring of Carey, In this letter, Spitzer wrote,. I was considering writing something that would acknowledge that I now judge the major critiques of the study as largely correct. I believe I owe the gay community an apology for my study making unproven claims of the efficacy of reparative therapy. Becker, , pars.

In this brief video , Chaz Bono discusses the difficulties of growing up identifying as male, while living in a female body. Gender is deeply cultural. Includes auditory, visual and chemical patterns. May be the result of early weaning. Causes include separation anxiety, fear-induced aggression and play aggression. This includes searching for the site, pre-elimination behavior of sniffing, scratching, etc. Housetraining involves modification of this behavior. In puppies, this includes tail-wagging, licking the dam's face, and following the dam closely. This may be inherent or acquired, e. Dogs, particularly in packs, may show predatory behavior in threatening and killing of livestock and, in some instances, humans. Much of the behavior is visual including posture, feather fluffing, tail carriage; some of it is auditory, especially in cats, but chemical communication via pheromones is the clincher. Includes establishment of the peck order, bulling by steers in feedlots, crowd pressure in the feeding of large groups of pigs, cannibalism in overcrowded communities, even self-immolation in lemming communities. The social stress that may follow abnormal group behavior may result in lowered production, reduction in disease resistance, or the expression of actual disease, e. See also obsessive-compulsive behavior. Occurs at different ages in different species and in different races and even breeds. In lower mammals, including the cat, complete removal of the neocortex of the female does not eliminate sexual receptivity, although the quality of the response may suffer. In male rats comparable decortication eliminates all sexual behavior, and these males show no signs of arousal in the presence of an estrous female. Partial decortication in the cat may eliminate successful mating behavior because of loss of sensory-motor integration, but the operation need not interfere with sexual arousal Beach In primates the cortex may play a major role in integration of sexual behavior. In general, the more important learning and memory are in sexual performance, the more important the neocortex is likely to be. It is apparent that control of sexual behavior is not vested in any single brain area. The evidence suggests rather that the entire nervous system is involved in the display of the normal pattern of sexual behavior. Although it has been pointed out that differences in patterns of sexual behavior are associated with differences in genetic background, this does not preclude the importance of experiential factors in determining the particular pattern displayed by the individual. The limits to which experience can modify the behavior pattern are, however, largely determined by genetic factors. In studying the influence of experiential factors on mating behavior, we are indirectly examining the variability allowed by genetic endowment. When males from two inbred strains of guinea pigs were separated from their mothers at the age of 25 days and reared in isolation, they did not display normal mating behavior patterns when tested as adults. For isolation to produce comparable effects in male guinea pigs of a heterogeneous stock, the animals had to be isolated beginning at 10 days of age. The experiment demonstrates the influence of genetic and experiential variables in determining patterns of sexual behavior. However, mother-deprived infants, if given an opportunity to interact with peers, develop essentially normal patterns of sexual behavior. The manner in which peer interaction fosters development of normal sexual behavior remains to be demonstrated. Female guinea pigs and rhesus monkeys reared in isolation also show deficiencies in reproductive behavior. Despite the bizarre social behavior and abnormal sexual behavior displayed by the isolated female rhesus, a number have mated with particularly capable males and have delivered viable young. It should be noted that the behavioral deficiency is not attributable to gonadal hormone deficiency in the isolated monkey or guinea pig. Although the exact nature and extent of the effects of isolation on sexual behavior have not been determined for the male rat, available evidence suggests that the impairment is not as profound as it is in the monkey Zimbardo A wide variety of experiences are capable of modifying sexual behavior in addition to the method of rearing just discussed. What has been demonstrated is that sexual behavior, in general, is subject to modification just as other aspects of behavior can be modified by varying experience. Thus despite heritability of sexual behavior patterns, dependence on hormonal stimulation, and the spinal reflex contribution to patterns of sexual behavior, the complete pattern can be blocked, enhanced, or modified by social and situational experience. The extent to which it can be modified by experience varies primarily with the species, sex, and age of the individual. Beach, Frank A. Psychological Review Physiological Review Pages in Paul H.

Valenstefn, Elliot S. Young, William C. Quarterly Review of Biology Science Zimbardo, Philip G. Social scientific writing on sexual behavior over the past century falls in three categories: It is now commonly accepted that the frequencies and techniques of sexual behavior vary widely among individuals and among religious, class, ethnic, educational, age, and sex categories in the same society Kinsey et al. As producers of literature on sexual behavior, social scientists are easily outnumbered by physicians, psychologists, physiologists, theologians, and philosophers, among others. The present article, rather than restricting itself to studies by social scientists, will conceptualize the content of this diverse literature from a social science perspective. These materials will be examined in terms of the social meanings of sexual behavior, the way the sexual enters as a component of social roles, the social norms governing recruitment to these eroticized roles, and their articulation with networks of the noneroticized roles that constitute some major social institutions. Reference will be made to social organizational arrangements for facilitating or inhibiting enactment of these roles. Sexual behavior participates in social action by contributing a motive, or a driving force of that action. Ratzenhofer , an early theorist of the sociology of sex, saw all motives of social contact as modifications of either the instinct of self-preservation or the sexual instinct. Moreover, as a component of social action, sexual behavior is also a way of expressing and conveying both individual and social meanings; that is, the meaning is not only that which an individual attributes to his act but also that which society has come to apply to the act Thomas These are by far the most popular scientific studies of sex, as measured by sales and published critical reviews. From a physicalist point of view, the presumption that all acts engaging the genitals are alternative ways of tapping the same reservoir of physiological energy justifies drawing them under the same rubric. Social science analyses of sexual behavior are primarily concerned with coital acts, both homosexual and heterosexual, which involve a relationship between human beings and are thus qualitatively different from other sexual behavior. Masturbation, nocturnal emissions, and bestiality claim social science attention only insofar as they affect either the occurrence of coitus or its meaning or become the object of institutional concern. According to this view, the energy problem is interwoven with that of the social meaning of sexual acts. Freudian theory of the economy of the libido uses the notion of sublimation to designate the rechanneling of sexual energy into cultural activities by shifting the object of cathexis; thus the theory interweaves motivational and meaningful aspects. Sexual behavior contains a nonverbal language through which an individual expresses and conveys meanings; sensory exploration and gestures outweigh words as sign and symbol vehicles. Removal of clothing beyond the degree necessary for coitus itself exemplifies the significance of tactile communication. Any sexual act may carry several social and personal meanings. For example, a morning erection may express unconscious concerns about death rather than sex Bergler Ford and Beach studied sexual behavior between species and across cultures, yet they granted priority to the physicalist approach by classifying sexual behavior according to modes of stimulation of the genitals. A consequence of this physical perspective is their tendency to measure the cause of sexual behavior in terms of tension reduction and to designate procreation as its principal social function. The procreative function loses its centrality for a social psychology of human sexual behavior in view of the empirical fact that less than one in a thousand human coital acts results in pregnancy and fewer are intended to do so Foote However, for sociology, the part of sexual behavior that is, in fact, procreative becomes significant because of both the demographic consequences and the institutional and organizational arrangements that become necessary for the birth and rearing of offspring Ellwood Sexual behavior as a role component, that is, as a component of social action under decisional and normative control, distinguishes human from animal sexuality. A social role—such as that of lover, of prostitute or client, of husband or wife, of young male delinquent or adult fellator A. This is what has been described as a transformation of sexuality into Eros Marcuse Sexuality becomes meaningful to the actor, and may be understood by the observer, in the context of these other aspects of the personality. An eroticized social role may be articulated with other roles in the social structure; for example, the role of the prostitute in her relation with a client may be meshed with her relatively nonerotic role in her relation with her madam or other employer. This perspective on role articulation follows Malinowski , who advocated an anthropological perspective that does not treat sex as a mere physiological transaction but studies its implication for lovemaking, its function as the nucleus of the family, the spells and magic that grow up around it, its effects upon, and how it is affected by, the legal system and the economic system. The variety of sexual meanings is, in part, dependent on other aspects of the role—that is, on other norms, affects, or meanings that define that role or other roles with which it is articulated in a personality or in a society. Kirkendall described how sex, while it may advance a deep interpersonal relation, may be exploitative as part of a casual relationship. With prostitutes, the relationship itself becomes the instrumental servant of its sexual component. Even in advancing a deep relation, however, sex may assume special meanings associated with the broader meaning of that relationship. Thus sex may be a weapon to destroy, a mode of defense, a bargaining point, or a form of self-assertion; negatively, it may be a form of self-denial Frank Components of an eroticized role may be malintegrated. A marriage contracted for social or economic advantages despite sexual incompatibility is a classic instance. Sexual behavior inconsistent with personal ethical standards may engender an internal struggle manifested in guilt feelings. If strains of this type become widespread, social standards may be readjusted I. Reiss Recruitment of partners to an eroticized role is governed by considerations of personality, social norms, and societal mechanisms of control. Personality variables affect the desire and ability of an individual to seek, as well as his desirability as, a sex-role partner. In the preparatory stage, an individual must be able to respond to excitation from internal and external psychological stimulation. This requires sensory, intellectual, motor, and glandular contributions to mechanisms of arousal. An individual must experience impetus to penetrate or desire to be penetrated, want to continue inplay, and, at culmination, experience orgastic peristalsis of genital structures. Much depends upon ability to tolerate regression in the service of the ego Fried Disturbances of sexuality are commonly classified in terms of frigidity, low potency, preference for masturbation or for sexual perversion, hypersexuality, and lack of sexual interest Eisenstein Special personality groups vary in interest in eroticized roles. Most of the erotic impulse of idiots is directed toward themselves and the remainder to objects of the same sex Potter Alcoholics lack sex interest, because, it has been argued, of repressed homosexuality Levine The aged tend to lose motivation for coitus Armstrong The evaluation of personal characteristics in recruitment is relative to the persons involved; that is, an individual not desirable to one partner may be desirable to another. For example, males generally prefer shorter females, and females generally prefer taller males. Women who want men near their own height, it has been argued, are expressing a need for ascendancy. Similarly, males who seek taller women are said to be seeking to possess the forbidden parent figure Beigel Social norms prescribe and proscribe which social types may recruit one another. Havelock Ellis , for example, wrote that in choosing a mate we tend to seek parity of racial and anthropological characteristics together with disparity of secondary sexual characteristics and complementarity of psychic characteristics. Under control of instinct, animals rarely depart from parity of species and disparity of secondary sexual characteristics. Mongrelization may be induced among domesticated animals but is extremely rare among wild animals despite opportunities. Man can, and sometimes does, engage in relations that the more constitutionally directed animals would refuse. Man may disregard species parity and practice bestiality, disregard secondary sexual disparity and practice homosexuality, and disregard psychic complementarity and establish neurotic sex relations. On the other hand, man may refuse relations because of sexual style, the status of the partner, or the beauty of the partner—a parity irrelevant to the animal. For man, the power of the social over biological determinants extends to the very definition of gender. Money et al. Rules for recruitment to coital relations in general parallel, but do not completely overlap with, those governing marital recruitment. Laws of exogamy define the inner social limits for recruitment of a marital partner. These are extensions of the incest taboo, which is a nearly universal taboo, with exceptions only in such cases as the Egyptian royal family, where brother-sister marriage was permitted, or among Azande nobles, where father-daughter marriage has been permitted. Laws of endogamy define the outer social limits. In human relations, however, endogamy controls potentially fertile relations within the same species. A number of individuals are virtually precluded from recruitment to eroticized heterosexual roles. This is the case with institutionalized populations in prisons or mental hospitals. Likewise, occupational conditions may separate individuals from the opposite sex. Hobos, being homeless, have less access to women, and thus they tend to frequent the lowest status prostitutes and to practice homosexuality. Social control of eroticized role recruitment contributes to the maintenance of the social structure; if society lacked such controls, random mating could disrupt the familial and economic lines of stratification of a society. Moreover, social control of recruitment may enable one social group to dominate another through its power to allocate sexual occasions and facilities. It may also be an internally integrative device, as it is among celibate monastics. According to Ross , such control is necessary to manage a smoldering antagonism that exists between the sexes as groups. Communication employed for recruitment to the eroticized role parallels the communication of arousal in the sex act. Token arousal announces sexual availability. Erotic communication relies heavily on movement, such as the inviting movements of the dance and the arousing tactile movements during coitus. Odors founded in the natural capryl odors and supplemented at the human level by perfumes act upon the deeper levels of consciousness Bloch Cosmetic means of communicating sexual interest include painting and tattooing as well as sexual mutilation. Socially stylized ceremonies of fertility or initiation may announce availability and effect arousal. A few rites, such as subincision, announce sexual availability but reduce sexual enjoyment or arousal potential for the subject Allen ; Westermarck Verbal communication supplements sensory communication in sexual behavior. Speech is so closely identified with sexuality that in some cultures it is forbidden or restricted between persons who are socially precluded from engaging in sexual relations Baker The more intimate a sexual matter, the less the likelihood of communication about it to nonerotic role partners. In many societies, socially structured mores about erotic communication bar young people from arousal and consummatory opportunities. Sexual norms may be learned inferentially by the young or by new social groups, such as immigrants, by observation of behaviors lacking primary erotic meaning, such as forms of dress and of association between the sexes Klausner Classified newspaper advertising and a specialized journalism directed to erotica have long been used for the recruitment of both heterosexual and homosexual partners. Deviant subgroups develop private signaling systems to cue a potential partner without revealing themselves to noninitiate spectators. For example, homosexuals may wear peculiar clothing the definition of which changes from time to time , intersperse their speech with a special argot, or perform certain gestures. They may position themselves to receive such signals by frequenting known haunts. Society not only exerts control over the recruitment of role partners but also attempts to control the types of sexual behaviors enacted and the occasions for their enactment. A quasi-formal control mechanism is exemplified among the Mondurucu by the gang rape to force a recalcitrant female to submit to male authority Murphy Norms also define those behaviors to which it is legitimate to recruit. Early studies of sexual behavior treated cross-cultural comparisons descriptively, presenting various behaviors, sexual art, and technical devices as curiosities Moll ; Krafft-Ebing ; Bloch Correlations between sexual behavior and the overarching cultural ethos allow inference about the types of sexual behaviors to which recruitment is approved in various cultural situations; that is, recruitment norms vary with the ethos. In matristic periods, dominated by a mother religion and exemplified by England after the first millennium, people have a horror of incest and are permissive regarding sex. Social control may be exerted by concrete organizational arrangements. The Nazis, while promoting a policy of sexual abstinence, provided youth camps in which sexual relations took place. Monasteries may debar their inmates from sexual opportunities. Child marriage commits the relationship before the erotic drive appears. The sexes may be physically and, therefore, socially isolated, as in a harem or school. Chaperonage is a way of supervising the young during their meetings. Systems of peer group pressures, such as those exerted by campus sororities or fraternities, encourage socially approved love relationships by subjecting them to ratings by age mates. These controls are more stringent among the upper classes, who have more to lose by a breakdown in the stratification system Goode Legal control takes the form of laws against homosexuality, adultery, sodomy, or pederasty—that is, against behaviors that violate rules governing recruitment to the eroticized role. In England, the Wolfenden Committee on homosexual offenses and prostitution gathered intelligence about sexual behavior from social scientists and psychiatrists as a basis for legislating on sexual recruitment. They concluded that it is the duty of the law not to concern itself with immorality as such but to confine itself to activities that offend against public order and decency. Thus, they recommended that homosexual relationships between adults by mutual consent and in privacy should not fall within the province of criminal law Great Britain. Throughout Anglo-American history, the methods of legal control of sex expression have varied much more than has the accepted doctrine of sexual morality May ; Mueller Sex education is a form of noncoercive, though formal, control. The medical profession in its efforts to control venereal disease, as well as religious groups in their efforts to maintain their own sexual norms, have been instrumental in founding organizations such as the American Society of Sanitary and Moral Prophylaxis in and the American Social Hygiene Association in , now the American Social Health Association. This latter association uses education to combat venereal disease, commercialized prostitution, and other conditions associated with sex delinquency among young people. Protest against efforts to enforce prevailing sexual mores and to control recruitment to the eroticized role is expressed in individual sexual deviance, the formation of groups of individuals with special sexual needs, and movements to change the prevailing mores. The sex offender uses illegitimate means, such as violence or disregard for the consent of the partner, to recruit to coital or noncoital sexual behaviors, or he recruits without regard to rules defining permitted sexual partners. Generally, these individuals are undersexed rather than oversexed. Freudian theory suggests that some sex offenders may be compensating for feelings of bodily damage or phallic inadequacy, or suffering from castration anxiety Hammer Most sex offenders are of average intelligence. Those arrested for incest, however, tend to be older men of subnormal intelligence and antisocial personalities. Apprehended distributors of obscene literature tend to be older, sexually inhibited men of average intelligence who are not hostile. Women are rarely arrested for sexual offenses in American society, except for violating norms regarding public solicitation. The role relations in primarily nonsexual delinquent groups may become eroticized, involving, for instance, group masturbation. Organizations of individuals whose physical status makes it difficult for them to recruit or be recruited to an eroticized role, such as dwarfs or the blind, may oppose prevailing sexual mores, as may those who, though not necessarily handicapped or abnormal in a clinical sense, have sexual requirements that are contrary to the norms. Typically, older men and women maintaining interest in sexual interest and activity could be therapeutic; it is a way of expressing their love and care for one another. Factors such as biological and psychological factors, diseases, mental conditions, boredom with the relationship, and widowhood have been found to contribute with the common decrease in sexual interest and activity in old age. National sex surveys given in Finland in the s revealed aging men had a higher incidence of sexual intercourse compared to aging women and that women were more likely to report a lack of sexual desire compared to men. Regression analysis, factors considered important to female sexual activity included: Both genders in the study agreed they needed good health, good sexual functioning, positive sexual self-esteem, and a sexually skilful partner to maintain sexual desire. Heterosexuality is the romantic or sexual attraction to the opposite sex. Heterosexual sexual practices are subject to laws in many places. In some countries, mostly those where religion has a strong influence on social policy , marriage laws serve the purpose of encouraging people to have sex only within marriage. Sodomy laws were seen as discouraging same-sex sexual practices, but may affect opposite-sex sexual practices. Laws also ban adults from committing sexual abuse , committing sexual acts with anyone under an age of consent , performing sexual activities in public, and engaging in sexual activities for money prostitution. Though these laws cover both same-sex and opposite-sex sexual activities, they may differ in regard to punishment, and may be more frequently or exclusively enforced on those who engage in same-sex sexual activities. Different-sex sexual practices may be monogamous , serially monogamous, or polyamorous , and, depending on the definition of sexual practice, abstinent or autoerotic including masturbation. Additionally, different religious and political movements have tried to influence or control changes in sexual practices including courting and marriage, though in most countries changes occur at a slow rate. Homosexuality is the romantic or sexual attraction to the same sex. People with a homosexual orientation can express their sexuality in a variety of ways, and may or may not express it in their behaviors. It is possible for a person whose sexual identity is mainly heterosexual to engage in sexual acts with people of the same sex. For example, mutual masturbation in the context of what may be considered normal heterosexual teen development. Gay and lesbian people who pretend to be heterosexual are often referred to as being closeted hiding their sexuality in "the closet". Making that orientation public can be called " coming out of the closet " in the case of voluntary disclosure or " outing " in the case of disclosure by others against the subject's wishes or without their knowledge. Among some communities called "men on the DL" or " down-low " , same-sex sexual behavior is sometimes viewed as solely for physical pleasure. Men who have sex with men , as well as women who have sex with women , or men on the "down-low" may engage in sex acts with members of the same sex while continuing sexual and romantic relationships with the opposite sex. People who engage exclusively in same-sex sexual practices may not identify themselves as gay or lesbian. In sex-segregated environments, individuals may seek relationships with others of their own gender known as situational homosexuality. In other cases, some people may experiment or explore their sexuality with same or different sex sexual activity before defining their sexual identity. People who have a romantic or sexual attraction to both sexes are referred to as bisexual. Pansexuality also referred to as omnisexuality [41] may or may not be subsumed under bisexuality, with some sources stating that bisexuality encompasses sexual or romantic attraction to all gender identities. Alex Comfort and others propose three potential social aspects of sexual intercourse in humans, which are not mutually exclusive: For example: A fertile couple may have intercourse while using contraception to experience sexual pleasure recreational and also as a means of emotional intimacy relational , thus deepening their bonding, making their relationship more stable and more capable of sustaining children in the future deferred reproductive. This same couple may emphasize different aspects of intercourse on different occasions, being playful during one episode of intercourse recreational , experiencing deep emotional connection on another occasion relational , and later, after discontinuing contraception, seeking to achieve pregnancy reproductive, or more likely reproductive and relational. Most world religions have sought to address the moral issues that arise from people's sexuality in society and in human interactions. Each major religion has developed moral codes covering issues of sexuality, morality, ethics etc. Though these moral codes do not address issues of sexuality directly, they seek to regulate the situations which can give rise to sexual interest and to influence people's sexual activities and practices. However, the effect of religious teaching has at times been limited. For example, though most religions disapprove of extramarital sexual relations , it has always been widely practiced. Nevertheless, these religious codes have always had a strong influence on peoples' attitudes to issues of modesty in dress, behavior, speech etc. On the other hand, some people adopt the view that pleasure is its own justification for sexual activity. Hedonism is a school of thought which argues that pleasure is the only intrinsic good. Human sexual activity, like many other kinds of activity engaged in by humans, is generally influenced by social rules that are culturally specific and vary widely. These social rules are referred to as sexual morality what can and can not be done by society's rules and sexual norms what is and is not expected. Some activities, known as sex crimes in some locations, are illegal in some jurisdictions, including those conducted between or among consenting and competent adults examples include sodomy law and adult-adult incest. Some people who are in a relationship but want to hide polygamous activity possibly of opposite sexual orientation from their partner, may solicit consensual sexual activity with others through personal contacts, online chat rooms , or, advertising in select media. Swinging , on the other hand, involves singles or partners in a committed relationship engaging in sexual activities with others as a recreational or social activity. Some people engage in various sexual activities as a business transaction. When this involves having sex with, or performing certain actual sexual acts for another person in exchange for money or something of value, it is called prostitution. Other aspects of the adult industry include phone sex operators, strip clubs , and pornography. Social gender roles can influence sexual behavior as well as the reaction of individuals and communities to certain incidents; the World Health Organization states that, "Sexual violence is also more likely to occur where beliefs in male sexual entitlement are strong, where gender roles are more rigid, and in countries experiencing high rates of other types of violence. The relation between gender equality and sexual expression is recognized, and promotion of equity between men and women is crucial for attaining sexual and reproductive health , as stated by the UN International Conference on Population and Development Program of Action: BDSM is a variety of erotic practices or roleplaying involving bondage , dominance and submission , sadomasochism , and other interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves as practicing BDSM, inclusion in the BDSM community or subculture is usually dependent on self-identification and shared experience. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers , extreme body modification enthusiasts, animal players , latex or rubber aficionados , and others. Bondage includes the restraint of the body or mind. A submissive is someone who gives up the control to a person who wishes to take control. Masochism means an individual who takes pleasure from their own pain or humiliation. Participants who exert sexual dominance over their partners are known as dominants or tops , while participants who take the passive, receiving, or obedient role are known as submissives or bottoms. Individuals are also sometimes abbreviated when referred to in writing, so a dominant person may be referred to as a "dom" for a man or a woman. Sometimes a woman may choose to use the female specific term "Domme". Both terms are pronounced the same when spoken. The precise definition of roles and self-identification is a common subject of debate within the community. In a study, the researchers state that BDSM is a sexual act where they play role games, use restraint, use power exchange, use suppression and pain is sometimes involved depending on individual s. According to the findings, one who participates in BDSM may have greater strength socially and mentally as well as greater independence than those who do not practice BDSM. Before any sexual act occurs, the partners must discuss their agreement of their relationship. They discuss how long the play will last, the intensity, their actions, what each participant needs or desires. The sexual acts are all recorded as consensual and pleasurable to both parties. In a study, interviewed BDSM participants have mentioned that the activities have helped to create higher levels of connection, intimacy, trust and communication between partners. The participants have remarked that they enjoy pleasing their partner in any way they can and many surveyed have felt that this is one of the best things about BDSM. It gives a submissive pleasure to do things in general for their dominant. Where a Dominant enjoys making their encounters all about the submissive. They enjoy doing things that makes their submissive happy. The findings indicate that the surveyed submissives and dominants found BDSM play more pleasurable and fun. The participants have also mentioned improvements in their personal growth, romantic relationships, sense of community and self, the dominant's confidence, and their coping with everyday things by giving them a psychological release. There are many laws and social customs which prohibit, or in some way affect sexual activities. These laws and customs vary from country to country, and have varied over time. They cover, for example, a prohibition to non-consensual sex, to sex outside marriage, to sexual activity in public, besides many others. Many of these restrictions are non-controversial, but some have been the subject of public debate. Most societies consider it a serious crime to force someone to engage in sexual acts or to engage in sexual activity with someone who does not consent. This is called sexual assault , and if sexual penetration occurs it is called rape, the most serious kind of sexual assault. The details of this distinction may vary among different legal jurisdictions. Also, what constitutes effective consent in sexual matters varies from culture to culture and is frequently debated. Laws regulating the minimum age at which a person can consent to have sex age of consent are frequently the subject of debate, as is adolescent sexual behavior in general. Some societies have forced marriage, where consent may not be required. Many locales have laws that limit or prohibit same-sex sexual activity. In the West, sex before marriage is not illegal [ example needed ]. There are social taboos and many religions condemn pre-marital sex. Those found guilty, especially women, may be forced to wed the sexual partner, publicly beaten, or stoned to death. Other studies have analyzed the changing attitudes about sex that American adolescents have outside marriage. Adolescents were asked how they felt about oral and vaginal sex in relation to their health, social, and emotional well-being. Overall, teenagers felt that oral sex was viewed as more socially positive amongst their demographic. The laws of each jurisdiction set the minimum age at which a young person is allowed to engage in sexual activity..

The Kinsey Institute has continued as a research site of important psychological studies for decades. At the time, the Kinsey reports were quite sensational.

Never before had the Definition of sexual behavior public seen its private sexual behavior become the focus of scientific scrutiny on such a large scale. The books, which were filled with statistics and scientific lingo, sold remarkably well to the general public, and people began to engage in open conversations about human sexuality.

In fact, these books were banned in some countries. Ultimately, the controversy resulted in Kinsey losing funding that he had secured from the Rockefeller Foundation to continue his research efforts Bancroft, Kinsey described a remarkably diverse range of sexual behaviors Definition of sexual behavior experiences reported by the volunteers participating in his research.

Behaviors that had once been considered exceedingly rare or problematic were demonstrated to be much more common and innocuous than previously Definition of sexual behavior Bancroft, ; Bullough, InWilliam Masters and Virginia Johnson published a book detailing the click of their observations of nearly people who agreed to participate in their study of physiological responses during sexual behavior.

Unlike Kinsey, who used personal interviews and surveys to collect data, Masters and Johnson observed people having intercourse in a variety of positions, and they observed people masturbating, manually or with the aid of a device. While this was occurring, researchers recorded measurements of physiological variables, such as blood pressure and respiration rate, as well as measurements of sexual arousal, such as vaginal lubrication and penile tumescence swelling associated with an erection.

In total, Masters and Johnson observed nearly 10, sexual acts as a part of their continue reading Hock, Based on these observations, Masters and Johnson divided the sexual response cycle into four phases that are fairly similar in men and women: The excitement phase is Definition of sexual behavior arousal phase of the sexual response cycle, and it is marked by erection of the penis or clitoris and lubrication and expansion of the vaginal canal.

During plateauDefinition of sexual behavior experience further swelling of the vagina and increased blood flow to the labia minora, and men experience full erection and often exhibit pre-ejaculatory fluid.

Both men and women experience increases in muscle tone during this time. Orgasm is marked in women by rhythmic contractions of the pelvis and uterus along with increased muscle tension.

In men, pelvic contractions are accompanied by a buildup of seminal fluid near the urethra that is ultimately forced out by contractions of genital muscles, i. Resolution is the relatively rapid return to an unaroused state accompanied by a decrease in blood Definition of sexual behavior and muscular relaxation. While many women can quickly repeat the sexual response cycle, men must pass through a longer refractory period as part of resolution.

The refractory period is a period of time that follows an orgasm during which Definition of sexual behavior individual is incapable of experiencing another orgasm.

In men, the duration of the refractory period can vary dramatically from individual to individual with some refractory periods as short as several minutes and others as long as a day. As men age, their refractory periods tend to span longer periods of time. Figure 4. This graph illustrates the different phases of the sexual response cycle as described by Masters and Johnson. Furthermore, they determined that the vagina is a very elastic structure that can conform to read more of various sizes Hock, Figure 5.

Click Definition of sexual behavior. Issues of sexual orientation have long fascinated scientists interested in determining what causes one individual to be heterosexual while another is homosexual. For many years, people believed that these differences arose because of different socialization and familial experiences.

Genetic and biological mechanisms have also been proposed, and the balance of research evidence suggests that sexual orientation has an underlying biological component. In aggregate, the data suggest that to a significant extent, sexual orientations are something with which we are born.

Remarkable sexual stamina

Regardless of how sexual Definition of sexual behavior is determined, research has made clear that sexual orientation is not a choice, but rather it is a relatively stable characteristic of a person that cannot be changed. Claims of successful gay conversion therapy have source wide criticism from the research community due to significant concerns with research design, Definition of sexual behavior of experimental participants, and interpretation of data.

As such, there is no credible scientific evidence to suggest that individuals can change their sexual orientation Jenkins, Robert Spitzer, the author of one of the most widely-cited examples of successful conversion therapy, apologized to both the scientific community and the gay community for his mistakes, and he publically recanted his own paper in a public letter addressed to the editor of Archives of Sexual Behavior in the spring of Carey, In this letter, Spitzer wrote.

I was considering writing something that would acknowledge that I now judge the major critiques of the study as largely correct. I believe I owe the gay community an apology for my study making unproven claims of the efficacy of reparative therapy.

Many people conflate sexual orientation with gender identity because of stereotypical attitudes that exist about homosexuality. In reality, these are two related, but different, issues. Generally, our gender identities correspond to our chromosomal and phenotypic sex, but this is not always the case. When individuals do not feel comfortable identifying with the gender associated with their biological sex, then they experience gender dysphoria.

Gender dysphoria is a diagnostic category in the fifth edition of the Definition of sexual behavior and Statistical Manual of Mental Disorders DSM-5 that describes individuals who do not identify as Definition of sexual behavior gender that most people would assume they are. This dysphoria must persist for at least six months and result in significant distress or dysfunction to meet DSM-5 diagnostic criteria.

In order for children to be assigned this diagnostic category, they must verbalize their desire to become the other gender. Approximately 1. Many people who are classified as gender dysphoric seek to live their lives in ways Definition of sexual behavior are consistent with their own gender identity.

Human sexual activityhuman sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality.

This involves dressing in opposite-sex clothing and assuming an opposite-sex identity. These individuals may also undertake transgender hormone therapy in an attempt to make their bodies look more like the opposite sex, and in some cases, they elect Definition of sexual behavior have surgeries to alter the appearance of their external genitalia to resemble that of their gender identity Figure 6.

Transgender people who attempt to alter their bodies through medical interventions such as surgery and hormonal therapy are called transsexual individuals. Not all transgender this web page choose to alter their bodies: Figure 6. Chaz Bono, a transgender male, is a well-known person who transitioned from female click male.

Like race, it is a social construction with real consequences, Definition of sexual behavior for those who do not conform to gender binaries.
