===Gender differences===
{{see also|Sex differences in psychology#Sexual behavior}}

Psychological theories exist regarding the development and expression of gender differences in human sexuality. A number of them (including [[neo-analytic]] theories, [[sociobiological]] theories, [[social learning theory]], [[social role theory]], and [[script theory]]) agree in predicting that men should be more approving of casual sex (sex happening outside a stable, committed relationship such as [[marriage]]) and should also be more [[promiscuous]] (have a higher number of sexual partners) than women. These theories are mostly consistent with observed differences in males' and females' attitudes toward casual sex before marriage in the United States. Other aspects of human sexuality, such as sexual satisfaction, incidence of [[oral sex]], and attitudes toward [[homosexuality]] and [[masturbation]], show little to no observed difference between males and females. Observed gender differences regarding the number of sexual partners are modest, with males tending to have slightly more than females.<ref name="Oliver & Hyde">{{cite book |last1=Oliver |first1=Mary Beth |last2=Hyde |first2=Janet S. |editor1-last=Baumeister |editor1-first=Roy F. |title=Social Psychology and Human Sexuality: Essential Readings |date=2001 |publisher=Psychology Press |isbn=978-1-84169-019-3 |pages=29–43 |chapter-url=https://books.google.com/books?id=2qsKNaqIsuUC&pg=PA29 |chapter=Gender Differences in Sexuality: A Meta-Analysis}}</ref>
