Sexual and romantic spectrums: Mostly straights and mostly gays/lesbians.

Sexual and romantic orientations and identities exist along a spectrum with varying degrees of compliance to traditional concepts of sex and romance. Recent investigations have focused on individuals who are not exclusive in their sexual and romantic lives-mostly straights and mostly gays/lesbians. Multi-disciplinary research reveals the diversity of individuals' internal and external sexual and romantic feelings and expressions.

Robust evidence for bisexual orientation among men.

The question whether some men have a bisexual orientation-that is, whether they are substantially sexually aroused and attracted to both sexes-has remained controversial among both scientists and laypersons. Skeptics believe that male sexual orientation can only be homosexual or heterosexual, and that bisexual identification reflects nonsexual concerns, such as a desire to deemphasize homosexuality. Although most bisexual-identified men report that they are attracted to both men and women, self-report data cannot refute these claims.

Gender Nonconformity of Bisexual Men and Women.

The degree to which bisexual-identified individuals are distinct from either heterosexual or homosexual individuals in their sexual orientation is an ongoing debate. We examined potential differences between these groups with respect to a strong correlate of sexual orientation, gender nonconformity (femininity in males, masculinity in females). Across pooled data, we compared self-reports of childhood gender nonconformity (n = 919) and adulthood gender nonconformity (n = 1265) and observer ratings of adulthood gender nonconformity (n = 915) between sexual orientations.

Young men's rationales for non-exclusive gay sexualities.

Recent evidence suggests it is useful to distinguish sexual identities among young men at the gay end of the spectrum because of group differences between primarily gay, mostly gay and gay orientations on several assessed physiological, behavioural and self-report measures. However, little is known about individuals' rationales for choosing sexuality labels beyond traditional gay or bisexual categories. We addressed this issue by interviewing 24 young men with a non-exclusive gay orientation about their sexual desires and histories, drawing on both qualitative and numeric data.

Gay, Mostly Gay, or Bisexual Leaning Gay? An Exploratory Study Distinguishing Gay Sexual Orientations Among Young Men.

This exploratory study assessed physiological, behavioral, and self-report measures of sexual and romantic indicators of sexual orientation identities among young men (mean age = 21.9 years) with predominant same-sex sexual and romantic interests: those who described themselves as bisexual leaning gay (n = 11), mostly gay (n = 17), and gay (n = 47). Although they were not significantly distinguishable based on physiological (pupil dilation) responses to nude stimuli, on behavioral and self-report measures a descending linear trend toward the less preferred sex (female) was significant regarding sexual attraction, fantasy, genital contact, infatuation, romantic relationship, sex appeal, and gazing time to the porn stimuli.
