Female promiscuity

Promiscuity tends to be frowned upon by many societies, expecting most members to have committed, long-term relationships with single partners. Female promiscuity is not unique to humans, and has been observed in other animals, including primates.

Most societies have historically been more critical of women's promiscuity than of heterosexual men's. Among women, as well as men, inclination for sex outside of committed relationships is correlated with sex drive, but social and cultural factors have also been observed to influence sexual behavior and opinion.

Studies have related sociosexual orientation to sex drive, especially in women, where the higher the sex drive the less restricted the sociosexual orientation, or interest in sex outside of committed relationships. Nevertheless, pertaining to the nature and nurture debate, there is some data emphasizing cultural factors, more so for women than for men. One review assessed that sociosexuality was affected almost equally by heredity and environment unshared with siblings; shared environment had relatively little effect.

Men tend to have higher sociosexuality scores and be more unrestricted than women across a variety of cultures. However, there is more variability in scores within each gender than between men and women, indicating that although the average man is less restricted than the average woman, individuals may vary in sociosexual orientation regardless of gender.

Contrary to popular belief, body esteem in women showed a significant positive correlation with sociosexual unrestrictedness. So did hip-to-waist ratio and two measures of virilization. Finally, still in the same study, alcohol consumption correlated, too, but it is unclear whether the latter promoted the former or vice versa, or if a third variable was at play.

Bisexual women tend to be less restricted in their sociosexual attitudes than both homo- and heterosexual women. In sociosexual behavior also, bisexual women reported being more unrestricted, followed by homo- and then heterosexual women.
