Mostly Heterosexual and Mostly Gay/Lesbian: Evidence for New Sexual Orientation Identities

A sample of 1,784 individuals responded to an online survey advertised on the Facebook social networking website. We explored
the sexual orientation continuum by focusing on three components: self-reported sexual orientation identity, sexual attraction,
and sexual partners. Results supported a 5-category classification of identity (heterosexual, mostly heterosexual, bisexual,
mostly gay/lesbian, gay/lesbian) in that two added identity labels (mostly heterosexual and mostly gay/lesbian) were frequently
chosen by participants and/or showed unique patterns of attraction and partners, distinct from their adjacent identities (heterosexual
and bisexual, and bisexual and gay/lesbian, respectively). Those who reported an exclusive label (heterosexual, gay/lesbian)
were not necessarily exclusive in other components; a significant minority of heterosexuals and the majority of gays/lesbians
reported some attraction and/or partners toward their nonpreferred sex. The five identity groups differed in attraction and
partners in a manner consistent with a continuous, rather than a categorical, distribution of sexual orientation. Findings
also supported a sexual orientation continuum as consisting of two, rather than one, distinct dimensions (same- and other-sex
sexuality). Having more same-sex sexuality did not necessarily imply having less other-sex sexuality, and vice versa. More
men than women were at the exclusive ends of the continuum; however, men were not bimodally distributed in that a significant
minority reported nonexclusivity in their sexuality.
