A Dutch study involving a large survey of 1,561 professionals, concluded that “The relationship between power and infidelity was the same for women as for men, and for the same reason.These findings suggest that the common assumption (and often-found effect) that women are less likely than men to engage in infidelity is, at least partially, a reflection of traditional gender-based differences in power that exist in society.” A 2010 study published in Journal of Marriage and Family found that there was a correlation between female pre-marital promiscuity and higher rates of divorce.However, observation of many species, from rabbits to fruit flies, has shown that females have more offspring if they mate with a larger number of males.
A number of studies, including Alfred Kinsey's, have concluded that the average age group in which women are the most active sexually is their mid-thirties, one study liberally estimating 27-45 as the limits of the age group (the average man peaks earlier).
One study in sexual antagonism suggested a possible genetic link between female androphilic promiscuity and male androphilia: Samoan tribal women exhibited a correlation between reproductive output and the likeliness of having androphilic grandsons, though not nephews (see also Fa'afafine).
In sociosexual behavior also, bisexual women reported being more unrestricted, followed by homo- and then heterosexual women.
Social power has been popularly associated with sexual infidelity among men; experimental psychologists have linked power with sexual infidelity among women also.
A male risked spending paternal investment on offspring who carried genetic material of another male rather than of his own.
