Description:
<jats:p>Kinsey argued that sexuality exists along a continuum from exclusive attraction to one sex or the other, with degrees of gradations of nonexclusivity in-between. Other than bisexuality and, recently, mostly heterosexuality, possibilities within the nonexclusive spectrum are seldom investigated, especially among men. In two studies presented here, an additional point, primarily heterosexual, in-between exclusively heterosexual and mostly heterosexual, is proposed. The three were distinguished among 92 young men based on self-reports of three sexual indicators (attraction, fantasy, genital contact); two romantic indicators (infatuation, romantic relationship); and sexual identity. Exclusively heterosexuals differed from the other two in having lower levels of pupil dilation to same-sex (but not other-sex) pornographic stimuli and of gender nonconformity, a proxy for sexual orientation. Primarily and mostly heterosexuals did not differ from each other on either measure but did differ in the extent to which mostly heterosexuals were considerably more likely to endorse same-sex sexuality. Results supported the uniqueness of mostly heterosexual men and, descriptively, primarily heterosexual men. The second longitudinal study found the exclusively heterosexual point was the most stable. Across the three, there was greater movement toward same-sex than other-sex sexuality. This is interpreted in light of the increasing acceptance of same-sex sexuality within the millennial generation.</jats:p>
