 Traditional cultural practices, such as enforced modesty and chastity, have tended to place restrictions principally on women, without imposing similar restrictions on men.According to psychoanalytic literature, the "Madonna–whore complex" is said to occur when a male desires sexual encounters only with women whom he sees as degraded ("whores") while he cannot desire sexually a respectable woman ("the Madonna").This was first described by Sigmund Freud.
