sex
For women: 1. A way to rebel. 2. A way to seduce a man to give her money, jewelry, etc. 3. A way to make a living. 4. A way to get pregnant. 5. A way to celebrate the emotional love between her & her SO (who might very well be a guy who will use her for a ONS). For men: The funnest thing in the world.
Woman: "Gve me jewelry & I'll let you fuck me". Man: "Sex is fun".
