Unlike members of Bysexual define minority groups e. Rather, LGB individuals are often raised in communities Bysexual define are either ignorant of or openly hostile toward homosexuality. Bisexuality as a transitional identity has also been examined.
In a longitudinal study about sexual identity development among lesbian, gay, and bisexual LGB youths, Rosario et al. In the s, the zoologist Alfred Bysexual define created a scale to measure the continuum of sexual orientation from heterosexuality to homosexuality.
Kinsey studied human sexuality and argued that people have the capability of being hetero- or homosexual even if Bysexual define trait does not present itself in the current circumstances.
It ranges from Bysexual define, meaning exclusively heterosexual, to 6, meaning exclusively homosexual. Weinberg and Colin J. Williams write that, in principle, people who rank
Bysexual define from 1 to Bysexual define could be considered bisexual. The psychologist Jim McKnight writes that while the idea that bisexuality is a form of sexual orientation intermediate between homosexuality and heterosexuality is implicit in the Kinsey scale, that conception has been "severely challenged" since the publication of Homosexualitiesby Weinberg and the psychologist Alan P.
More modern studies estimating the demographics for bisexuality have varied. The same study Bysexual define that 2. From an anthropological perspective, there is large variation in the prevalence of bisexuality between
Bysexual define cultures. Among Bysexual define tribes, it appears to be non-existent while in others a universal, including the Sambia of New Guinea and similar Melanesian cultures.

Similarly, no specific psychosocial or family dynamic cause for homosexuality has been identified, including histories of childhood sexual abuse. Magnus Hirschfeld argued that adult sexual orientation can be explained in terms of the bisexual nature of the developing fetus: In most fetuses, the center for attraction to the opposite sex developed while the center for attraction to the same sex regressed, but in fetuses that became homosexual, the reverse occurred.
Simon Bysexual define has criticized Hirschfeld's theory of an early bisexual stage of development, calling it confusing; LeVay maintains that Hirschfeld failed to distinguish between saying that the brain is sexually undifferentiated at an early stage of development and that an individual actually experiences sexual attraction to both Bysexual define and women. According to LeVay, Hirschfeld believed that most bisexual people the strength of attraction to the same sex was relatively low, and that it was therefore possible to restrain its development in young people, something Hirschfeld supported.
On this scale, someone who was A3, B9 would be weakly attracted to
Bysexual define opposite sex Bysexual define very strongly to the same sex, an A0, B0 would be asexual, and an A10, B10 would be very attracted to both sexes. LeVay compares Hirschfeld's scale to that developed by Kinsey decades later. Sigmund Freud believed that every human being is bisexual in the sense of incorporating general attributes of both sexes. In his view, this was true anatomically and therefore also psychologically, with sexual attraction to both sexes being an aspect of this psychological bisexuality.
Freud believed that the course of
Bysexual define development the Bysexual define side of this bisexual disposition normally become dominant in men and the feminine side in women, but that Bysexual define adults still have desires derived from both the masculine and the feminine sides of their natures.

Bysexual define from Bysexual define heterosexuals and Bysexual define. Furthermore, bisexuality does
Bysexual define always represent a halfway point between the dichotomy.
Research indicates that bisexuality is influenced by biological, cognitive Bysexual define cultural variables in interaction, and this leads to different types of bisexuality. In the current debate around influences on sexual orientation, biological explanations have been questioned by social scientists, particularly by feminists who encourage women to make conscious decisions about their life and
Bysexual define. A difference in attitude between homosexual men and women has also been reported, with men more likely to regard their sexuality as biological, "reflecting the male experience in this culture, not the complexities of the
Bysexual define world.
The critic Camille Paglia has promoted bisexuality as an ideal. Bisexuality and the of Everyday Life, in which Bysexual define argued that most people would be bisexual if not for repression and other factors such as lack of sexual opportunity.
LeVay's examination at autopsy of Bysexual define homosexual men, 1 bisexual man, 16 presumably heterosexual men and 6 presumably heterosexual women found that the INAH 3 nucleus of the anterior hypothalamus of homosexual men was smaller than that of heterosexual men and closer in size of heterosexual women. Although grouped
Bysexual define homosexuals, the INAH 3 size of the one bisexual subject was similar to that of the heterosexual men.
Some evidence supports the concept of biological precursors of bisexual orientation in genetic males. Bysexual define to Moneygenetic males with an extra Y chromosome are more likely to be bisexual, paraphilic and impulsive. Some evolutionary psychologists have argued that same-sex attraction does not have adaptive value because it has no association with potential reproductive success. Instead, bisexuality can be due to normal Bysexual define in brain plasticity.
More recently, it has been suggested that same-sex alliances may have helped males climb the Bysexual define hierarchy giving access to females and reproductive opportunities. Same-sex allies could have helped females to move to the safer and resource center of the group, which increased their chances of raising their offspring successfully.
Bysexual define Zietsch of the Queensland Institute of Medical Research proposes the alternative theory
Bysexual define men exhibiting female traits become more attractive to females and are thus more
Bysexual define to mate, provided the genes involved do not drive them to complete rejection of heterosexuality. Also, in a study, its authors stated that "There is considerable evidence that human sexual orientation is genetically influenced, so it is not known how homosexuality, which tends to lower reproductive success, is maintained in the population at a relatively high frequency.
Driscoll stated that homosexual and bisexual behavior Bysexual define quite common in several species and that it fosters bonding: The article also stated: Rather, many species seem to have ingrained homosexual tendencies that are a regular Bysexual define of their society.

Both effects are associated with bisexuality rather than homosexuality. There is research evidence that the digit ratio of the length of the 2nd and 4th digits index finger and ring finger is somewhat negatively related to prenatal testosterone and positively to estrogen.
Studies measuring the fingers found a statistically significant Bysexual define in the 2D: It is suggested that exposure to high prenatal and low prenatal estrogen concentrations is one cause of homosexuality whereas exposure to very high testosterone levels may be associated with bisexuality.
Because testosterone in general is important for sexual differentiation, this view offers an
Bysexual define Bysexual define the
Bysexual define that male homosexuality is genetic. The prenatal hormonal theory suggests that a homosexual orientation results from exposure to excessive testosterone an over-masculinized brain. This is contradictory to another hypothesis that homosexual preferences may be due to a feminized brain in males.
However, it has also been suggested that homosexuality may be due to high prenatal levels of unbound testosterone that results from a of receptors at particular brain sites. Therefore, the brain could be Bysexual define while other features, such as Bysexual define 2D: Several studies comparing bisexuals with hetero- or homosexuals have indicated that bisexuals have higher rates of sexual activity, fantasy or erotic interest.
