Sexual Strategies Across Sexual Orientations

Abstract The psychological intersection of biological sex, personality, and sexual orientation represents a unique prospect for investigating the evolution of human mating strategies. Evolved sex differences in human psychology may encounter different mating environments within homosexual and heterosexual contexts. The personality traits of homosexuals, if different from heterosexuals, may influence human mating dynamics in revealing ways. In the current study, 5,310 men (5,083 heterosexuals, 131 homosexuals, and 96 bisexuals) and 7,589 women (7,240 heterosexuals, 143 homosexuals, and 206 bisexuals) across four major world regions completed personality and sexuality self-report surveys. Consistent with previous research, sociosexual behavior (e.g., number of one-night stands) and personality traits (e.g., masculinity and openness to experience) varied across sexual orientation. In addition, personality traits were predictably related to sociosexual behavior. However, variability in personality traits did not account for the observed differences in sociosexual behavior across sexual orientation.
