Masturbation
It appears that females are less likely to masturbate while in a heterosexual relationship than men. Both sexes occasionally engage in this activity, however, even when in sexually active relationships.  Popular belief asserts that individuals of either sex who are not in sexually active relationships tend to masturbate more frequently than those who are; however, much of the time this is not true as masturbation alone or with a partner is often a feature of a relationship.  Contrary to conventional wisdom, several studies actually reveal a positive correlation between the frequency of masturbation and the frequency of intercourse as well as the number of sex partners. One study reported a significantly higher rate of masturbation in gay men and women who were in a relationship.
