C.s. Lewis said this quote

“ A society in which conjugal infidelity is tolerated must always be in the long run a society adverse to women. Women, whatever a few male songs and satires may say to the contrary, are more naturally monogamous than men; it is a biological necessity. Where promiscuity prevails, they will therefore always be more often the victims than the culprits. Also, domestic happiness is more necessary to them than to us. And the quality by which they most easily hold a man, their beauty, decreases every year after they have come to maturity, but this does not happen to those qualities of personality —women don’t really care two cents about our looks—by which we hold women. Thus in the ruthless war of promiscuity women are at a double disadvantage. They play for higher stakes and are also more likely to lose. I have no sympathy with moralists who frown at the increasing crudity of female provocativeness. These signs of desperate competition fill me with pity. ”
