Studies of female sexuality conducted by sex researchers in the United States since indicate that human females in general are concerned with their sexual well-being and are capable of sexual response parallel to sexuality of males. Across cultures human general and pdf western societies in particular, females engage in extramarital affairs regularly, regardless of punishment by humna or social disapproval.

Across cultures in general and in western societies in particular, females engage in extramarital affairs regularly, regardless of punishment by males or social disapproval. Families are usually concerned with marriage arrangements only insofar as those arrangements are economically or politically advantageous, but females most often have a voice in arranged marriages.
Extended families also concentrate on a couple's future reproduction rather than on sexual exclusivity. Although marriage for females is often compromised by male or family reproductive interests which may not in fact differ from female interests , females appear to exercise their sexuality with more freedom than has previously been suggested.
