Relationships with age disparities have been observed with both men and women as the older or younger partner. In various cultures, older men and younger women often seek one another for sexual or marital relationships.[5] Older women sometimes date younger men as well,[6] and in both cases wealth and apparent physical attractiveness are often relevant.[7] Because most men are interested in women in their 20s, adolescent boys are generally sexually interested in women somewhat older than they are.[8] Older men also display an interest in women of their own age.[9] However, research suggests that relationship patterns are more influenced by women's preferences than men's.[8][10][11]
