Sex, Sexual Orientation, and the Necessity of Physical Attractiveness and Social Level in Long-Term and Short-Term Mates

In comparison to biological sex differences and mate preferences, differences in sexual orientation and mate preferences have received limited attention in the literature. The aim of the current experiment was to explore the relationship between biological sex and sexual orientation on the necessity of a long-term and short-term mate's physical attractiveness and social level. Three hundred and seven participants recruited from an Australian university and the wider community completed an online questionnaire assessing necessities of mate characteristics. Results of independent-measures ANOVAS showed that heterosexual men considered a long-term mate's physical attractiveness significantly more of a necessity than heterosexual women. Additionally, individuals of a homosexual sexual orientation considered the social level of a long-term mate significantly more of a necessity than individuals with a heterosexual sexual orientation, but not individuals of a bisexual sexual orientation. Finally, results showed that individuals of a heterosexual sexual orientation considered the physical attractiveness of a short-term mate significantly more of a necessity than did individuals of a homosexual sexual orientation and individuals of a bisexual sexual orientation. Results of the current study suggest research should not just assume equivalence of mate preferences between individuals of differing sexual orientations.
