In cultures where food, belongings and child rearing are shared, sex is shared amongst the group. In societies where there is more of a sense of ownership, hoarding and individuality, men own their wives and have a sense of possession of their wives' vaginas. They also see their offspring as their possessions. These cultures are polygynous (or "monogamous" with much cheating). Men who sleep around and cheat and pay for prostitutes are seen as studs. Women who sleep around or are paid as sex workers are seen as sluts, fallen women, depraved and hysterical. Homosexual men are seen as weak, and lesbians are invisible.
It seems to me, even though our current culture is not hunter/gatherer or horticultural, current feminist thought, and reliable birth control allows for a return to women being autonomous and feeling a sense of entitlement to make the choice whom to fuck.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
