Abstract; It has been recently argued that heterosexual men, as opposed to heterosexual women, find same-sex attraction and contact desirable in a partner. The current paper employs an online sample of 775 heterosexual participants in order to examine this sex difference and assess its evolutionary implications. Results showed that just over half of heterosexual men preferred some level of same-sex attraction and contact in a female partner. On the other hand, the vast majority of heterosexual women did not prefer same-sex attraction and contact in a partner. This sex difference remained significant after controlling for religiosity and porn consumption. In addition, it was found that men preferred same-sex attraction and contact more in a short-term than in a long-term partner. Moreover, men indicated a stronger preference for their partners to engage in same-sex contacts where they would also participate, than to engage in same-sex contacts without themselves participating. It was also found that men did not consider same-sex attraction to be an important selection criterion for a partner.
