Abstract
Individuals who report mostly heterosexual orientations (i.e., mostly sexually attracted to the opposite sex, but occasionally attracted to the same sex) outnumber all other non-heterosexual individuals combined. The present study examined whether mostly heterosexual men and women view same- and other-sex sexual stimuli differently than exclusively heterosexual men and women. A novel eye-tracking paradigm was used with 162 mostly and exclusively heterosexual men and women. Compared to exclusively heterosexual men, mostly heterosexual men demonstrated greater attention to sexually explicit features (i.e., genital regions and genital contact regions) of solo male and male–male erotic stimuli, while demonstrating equivalent attention to sexually explicit features of solo female and female–female erotic stimuli. Mediation analyses suggested that differences between mostly and exclusively heterosexual profiles in men could be explained by mostly heterosexual men’s increased sexual attraction to solo male erotica, and their increased sexual attraction and reduced disgust to the male–male erotica. No comparable differences in attention were observed between mostly and exclusively heterosexual women—although mostly heterosexual women did demonstrate greater fixation on visual erotica overall—a pattern of response that was found to be mediated by reduced disgust.
