Sexual self-schema (SSS) – the cognitive frameworks that organize information about one’s own sexuality – are known to guide sexual attitudes and behaviors, and are thus likely to interact with the kinds of people to whom one is attracted (i.e., heterosexual, same-sex/gender, monosexual or bisexual patterns of attraction). Extending prior work highlighting differences in SSS between discrete sexual orientation identity groups, we investigated associations between multiple aspects of SSS and attraction patterns among 602 young adults with a range of sexual orientations. Generally, there were more similarities than differences in SSS across individuals with monosexual vs. bisexual patterns of attraction. However, a few significant effects emerged, with significant differences across sex/gender. For women, the greatest differences were seen between romantic self-schema in women with asexual vs. non-asexual patterns of attractions, while women with bisexual attractions were relatively similar to those with monosexual attractions (either exclusively heterosexual or same-sex/gender attracted). For men, however, the greatest differences were seen between open/liberal self-schema in exclusively same-sex/gender attracted men vs. either bisexual or heterosexually attracted men. Broadly, these findings point to subtle sex/gender differences in how bisexual attractions interact with one’s conceptualization of one’s sexual self. Also, a non-trivial portion (22%) of participants reported attractions to gender non-binary people, and these attractions significantly predicted different SSS, suggesting the need to measure attractions outside of the gender binary.
