Heterosexuality 14084 225571053 2008-07-14T10:47:47Z AnonMoos 21047 see [[User talk:Mrg3105]] [[Image:Love - Engagement.jpg|thumbnail|right|300px|A man and a woman holding hands]] '''Heterosexuality''' is [[sexual attraction|sexual]], [[emotion]]al and [[social]] relationship between opposite [[sex]]es, usually applied to [[human]] beings, but observed in [[mammal]]s in general, and is the only possible reproductive [[sexual orientation]] among humans without use of [[Assisted reproductive technology|medical assistance]]. The associations with [[romantic love]] and [[Sexual identity|identity]] in addition to its original, exclusively sexual meaning dates back to early human societies and [[gender role]] separation. As such, gender role separation has been the subject of considerable scholarly commentary and study in human societies since earliest written records. Heterosexuality has been more intensely studied by [[medicine]] and later [[biology]] disciplines, and more recently that of [[psychology]]. ==Etymology== ''Hetero-'' comes from the Greek word ''heteros'', meaning "different" or "other", from "one at one, together"<ref>p.345, Klein</ref> and the Latin for [[sex]] (that is, characteristic sex or [[sexual differentiation]]). The term "''heterosexual''" was first published in [[1892]] in C.G. Craddock's translation of [[Richard von Krafft-Ebing|Krafft-Ebbing's]] "[[Psychopathia_Sexualis_(book)#Psychopathia_Sexualis|Psychopathia Sexualis]]". The noun came into use from early 1920s, but did not enter common use until 1960s. Colloquial shortening "hetero" is attested from 1933. Heterosexuality is first recorded in 1900.<ref>p.22, Mills</ref> [[Heterosexuality#References|<nowiki>[2]</nowiki>]] ''"Heterosexual"'' was first listed in Merriam-Webster's ''New International Dictionary'' as a [[Medical terminology|medical term]] for "morbid sexual passion for one of the opposite sex", however in 1934 in their ''Second Edition Unabridged'' it is a "manifestation of sexual passion for one of the opposite sex; normal sexuality". (p.92, Katz) The adjective ''heterosexual'' is used for [[intimate relationship]]s and/or [[human sexual behavior|sexual relations]] between male and female individuals. ==Terminology== The current use of the term ''heterosexual'' has its roots in the broader 19th century tradition of personality taxonomy. It continues to influence the development of the modern concept of [[sexual orientation]], and can be used to describe individuals' sexual orientation, sexual history, or self-identification. Some reject the term "heterosexual" as the word only refers to one's sexual behavior and does not refer to non-sexual romantic feelings. As a result, the terms ''straight'' is sometimes preferred when discussing a person of this [[sexual orientation]], whose sexual history is predominated by this behavior, or who identifies as such, and to differentiate with other sexual orientations that strangely lack the intuitively suggested term "bent". Some opposite-sex oriented people personally prefer the term "heterosexual" rather than "straight", as they may perceive the former as describing a sexual orientation and the latter as describing a cultural or socio-political group with which they do not identify.{{Fact|date=January 2008}} The term "''heterosexual''" is suggested to have come into use as a [[neologism]] after, and opposite to the word "homosexual" by [[Karl Maria Kertbeny]] in 1868. ==History and demographics== {{seealso|Demographics of sexual orientation}} The prevalence of exclusive heterosexuality has varied over the centuries and also from culture to culture. The history of heterosexuality is part of the [[history of sexuality]]. That history and science derivative of it is far from complete. Owing to complications of human politics and prejudice, coupled with the malleable nature of human behaviour, it will be some time before the history and nature of all forms of human sexual behaviour are truly known. ==Academic study== Heterosexuality, like any forms of identity is very subjective. In Western society, one is generally thought of as heterosexual if he or she derives his or her erotic and/or sexual stimulation from people of the opposite sex. In other cultures a heterosexual man may engage in homosexual intercourse provided that he keeps the role traditionally assigned to his [[sex]] during intercourse and his [[gender]] during the surrounding relationship.{{Fact|date=July 2008}} Also, in some cultures a heterosexually identifying man may assume any role during homosexual congress as a social action provided he maintain a relationship with a woman in his family life.{{Fact|date=July 2008}} Cultural allowances such as this have been historically rarer amongst women, but more recently have been tolerated more than the male equivalents largely because of its connection to some schools of [[feminism]]. ===Biological=== {{main|Biology and sexual orientation}} ====Prenatal hormonal theory==== {{main|Prenatal hormones and sexual orientation}} The neurobiology of the masculinization of the brain is fairly well understood. Estradiol and testosterone, which is catalyzed by the enzyme 5α-reductase into dihydrotestosterone, act upon androgen receptors in the brain to masculinize it. If there are few androgen receptors (people with [[Androgen insensitivity syndrome]]) or too much androgen (females with [[Congenital adrenal hyperplasia]]), there can be physical and psychological effects.<ref>Vilain, E. (2000). Genetics of Sexual Development. Annual Review of Sex Research, 11:1-25</ref> It has been suggested that both male and female heterosexuality are results of variation in this process.<ref>Wilson, G. and Rahman, Q., (2005). Born Gay. Chapter 5. London: Peter Owen Publishers</ref> In these studies heterosexuality in females is linked to a lower amount of masculinization than is found in lesbian females, though when dealing with male heterosexuality there are results supporting both higher and lower degrees of masculinization than homosexual males. (See the main article for further details.) ====Physiological differences in heterosexual persons==== :''See: [[Homosexuality|Physiological differences]]'' ====Natural selection==== An array of opinion holds that much human behavior is ultimately explainable in terms of [[natural selection]]. From this point of view, the shifting social balance between heterosexual and homosexual desire has evolved more as a fitter survival strategy for the species than either an exclusively heterosexual or homosexual configuration of desire. ====Heterosexual behaviors in animals==== In the animal kingdom, [[sexual reproduction]] results from heterosexual [[sexual intercourse|coitus]] between sexually mature partners. ===Psychological=== {{main|Sexual orientation}} ====Behavioral studies==== {{main|Kinsey Reports}} At the beginning of the 20th century, early theoretical discussions in the field of [[psychoanalysis]] posited original [[bisexuality]] in human psychological development. Quantitative studies by [[Alfred Kinsey]] in the 1940s and [[Fritz Klein|Dr. Fritz Klein]]'s sexual orientation grid in the 1980s find distributions similar to those postulated by their predecessors. Many modern studies, most notably ''Sexual Behavior in the Human Male'' by [[Alfred Kinsey]], have found that the majority of humans have had both heterosexual and homosexual experiences or sensations and are bisexual. Contemporary scientific research suggests that the majority of the human population is bisexual, adhering to a fluid sexual scale rather than a category, as Western society typically views sexual nature. However, social pressures influence people to adhere to categories or labels rather than behave in a manner that more closely resembles their nature as suggested by this research. Kinsey himself, along with current sex therapists, focused on the historicity and fluidity of sexual orientation. Kinsey's studies consistently found sexual orientation to be something that evolves in many directions over a person's lifetime; rarely, but not necessarily, including forming attractions to a new sex. Rarely do individuals radically reorient their sexualities rapidly—and still less do they do so volitionally—but often sexualities expand, shift, and absorb new elements over decades. For example, socially normative "age-appropriate" sexuality requires a shifting object of attraction (especially in the passage through adolescence). Contemporary [[queer theory]], incorporating many ideas from [[social constructionism]], tends to look at sexuality as something that has meaning only within a given historical framework. Sexuality, then, is seen as a participation in a larger social discourse and, though in some sense fluid, not as something strictly determinable by the individual. Most sexual orientation specialists follow the general conclusion of Alfred Kinsey regarding the sexual continuum, according to which a minority of humans are exclusively heterosexual or [[homosexuality|homosexual]], and that the majority are [[bisexuality|bisexual]]. The consensus of psychologists is that sexual orientation, in most individuals, is shaped at an early age and is not voluntarily changeable. Other studies have disputed Kinsey's methodology. "His figures were undermined when it was revealed that he had disproportionately interviewed homosexuals and prisoners (many sex offenders)."<ref>Tom Bethell (April 2005). "Kinsey as Pervert".</cite> ''American Spectator'', '''38''', 42-44. ISSN 0148-8414.</ref><ref>Julia A. Ericksen (May 1998). "With enough cases, why do you need statistics? Revisiting Kinsey's methodology".</cite> ''The Journal of Sex Research'' '''35''' (2): 132-40, ISSN 0022-4499.</ref> However, Kinsey's idea of a sexuality continuum still enjoys acceptance today and is supported by findings in the human and [[animal kingdom]]s, including biological studies of structural brain differences between those belonging to different sexual orientations. Sexologists have attributed discrepancies in some findings to negative societal attitudes towards a particular sexual orientation. For example, people may state different sexual orientations depending on whether their immediate social environment is public or private. Reluctance to disclose one's actual sexual orientation is often referred to as "being in the closet." Individuals capable of enjoyable sexual relations with both sexes or one sex may feel inclined to restrict themselves to heterosexual or homosexual relations in societies that stigmatize same-sex or opposite-sex relations. In traditional societies, individuals are often under heavy social pressure to marry and have children, irrespective of their desired sexual orientation. Although the concept of three basic sexual orientations is widely recognized, a small minority maintain that there are other legitimate sexual orientations besides homosexuality, bisexuality and heterosexuality.{{Fact|date=June 2008}} These may include significant or exclusive orientation towards a particular type of transsexual or transgender individual (e.g. female-to-male transsexual men), intersexed individuals, or those who identify as non-gendered or other-gendered. ===Nature versus nurture=== The considerable "[[Nature versus nurture]]"-debate exists over whether predominantly biological or psychological factors produce sexual orientation in humans. Candidate factors include [[Biology and sexual orientation#Empirical studies|genes]] and the exposure of fetuses to certain [[Biology and sexual orientation#Early fixation hypothesis|hormones]] (or lack thereof). Historically, Freud and many other psychologists, particularly in psychoanalytic or developmental traditions, speculated that formative childhood experiences helped produce sexual orientation; as an example Freud believed that all human teenagers are predominantly bisexual{{Fact|date=January 2008}}<!-- said "homosexual" when first added, 17:36, 11 December 2006; changed 10:39, 2 September 2007 by anon-IP --> and transition to heterosexuality in adulthood; those who remain homosexual as adults he believed had experienced some [[traumatic event (psychological)|traumatic event]] that arrested their sexual development; however, he did believe all adults, even those who had no traumatic experience, still retained latent homosexuality to varying degrees. Although there is currently no general medical consensus, one theory is that biological factors—whether genetic or acquired ''in utero''—produce characteristically homosexual childhood experiences (such as atypical gender behavior experiences), or at least significantly contribute to them. The APA currently officially states that sexual orientation is not chosen and cannot be changed, a radical reversal from the recent past, when non-normative sexuality was considered a deviancy or mental ailment treatable through institutionalization or other radical means. ===Critique of studies=== The studies performed in order to find the origin of sexual orientation have been criticized for being too limited in scope, mostly for focusing only on heterosexuality and homosexuality as two diametrically opposite poles with no orientation in between. It is also asserted that scientific studies focus too much on the search for a biological explanation for sexual orientation, and not enough on the combined effects of both biology and psychology. In a brief put forth by the [[Council for Responsible Genetics]], it was stated that [[sexual orientation]] is not fixed either way, and on the discourse over sexual orientation: "Noticeably missing from this debate is the notion, championed by [[Alfred Kinsey|Kinsey]], that human sexual expression is as variable among people as many other complex traits. Yet just like intelligence, sexuality is a complex human feature that modern science is attempting to explain with genetics... Rather than determining that this results from purely biological processes, a trait evolves from developmental processes that include both biological and social elements. In addition, scientists rarely take into consideration sexual preferences that are not described by the two poles heterosexual and homosexual 'in hopes of maximizing the chance that they will find something of interest.'"<ref>{{cite web|url= http://www.gene-watch.org/programs/determinism/SO.html|title= Brief on Sexual Orientation and Genetic Determinism'}}</ref> According to the [[American Psychological Association]] (APA), there are numerous theories about the origins of a person's sexual orientation, but some believe that "sexual orientation is most likely the result of a complex interaction of environmental, cognitive and biological factors," and that genetic factors play a "significant role" in determining a person's sexuality.[[Heterosexuality#References|<nowiki>[5]</nowiki>]] ==Symbolism== [[Image:HeteroSym-pinkblue2.svg|thumbnail|right|150px|One common version of a Heterosexuality symbol]] History of heterosexual symbolism dates back to the earliest artefacts of humanity which included ritual fertility carvings and primitive rock art. This was later expressed in the symbolism of [[fertility rites]] and [[Polytheism#Historical_polytheism|polytheistic worship]] which often included images of human [[Sex organ|reproductive organs]]. The modern symbols of heterosexuality in the societies derived from Europe are still referenced to the symbols used in these ancient beliefs, with the image in this section being a combination of the symbol for [[Mars]] as the definitive [[male]] [[stereotype]] of a [[warrior]], and [[Venus#Venus_in_human_culture|Venus]], the Roman goddess of love. ==Slang== The term "''[[straight]]''" originated as a mid-20th century [[gay slang]] term for heterosexuals, ultimately coming from the phrase "''to go straight''" (as in "straight and narrow"), or stop engaging in homosexual sex.[[Heterosexuality#References|<nowiki>[3]</nowiki>]] One of the first uses of the word in this way was in [[1941]] by author [[G. W. Henry]]. Henry's book concerned conversations with homosexual males and used this term in connection with the reference to ''[[ex-gay]]s''. It currently simply is a colloquial term for "heterosexual" having, like many words, changed in primary meaning over time. The term ''[[breeder (slang)|breeder]]'', a word which is [[Animal husbandry|normally applied to animals]], is sometimes used by [[lesbian]] or [[gay]] persons to describe heterosexuals in a negative or humorous way.{{Fact|date=July 2008}} ==See also== <!--These should be links to articles not otherwise mentioned in the text, but within the subject area of the article-->{{Portal|Sexuality}} * [[Human sexuality]] ==Footnotes== {{reflist}} ==References== * Wikholm, Andrew, [http://www.gayhistory.com/rev2/words/heterosexual.htm Words: Heterosexual.] Gay History.com.
