Both males and females, benefit from sexual variety (though females only if a source of resources is secured). When females engage in promiscuity, as human female ancestors may have, it heightens men's concern about [[paternity assurance]] as they would lose their resources when investing in someone else's offspring (from the male gene's perspective). Thus, it motivates males to constrain female sexuality. This constitutes a [[sexual conflict]], opposing female [[whoring]] and engagement in [[pump and dump]] on the one side for increasing sexual variety, and culture limiting sexual variety for females on the other. | Both males and females, benefit from sexual variety (though females only if a source of resources is secured).

Female promiscuity gives rise to '''sperm competition''' as it means the sperm needs to compete inside the [[vagina]] and possibly also affecting shape of the [[penis]] so as to be able to scoop out competing sperm. There is some (limited) evidence of female promiscuity in humans, which may have been more behavior of a fast [[life history]] speed past, but still show in certain innate behaviors today such as the male desire for [[paternity assurance]], as well the peculiar size and shape of the human penis. | |||
