Men never lose their erection in the middle of things. Women always love having their nipples bitten right away, while they're still warming up. No one ever gets sore or cramp. Women love laying there and getting pounded in the same position for hours at a time. Especially when taking on three, four, or ten guys in a row.
All women love facials.
The man's dick never accidentally slips out at the wrong moment. A straight woman will go mad with ecstasy when a lesbian eats her out. Two or more high school girls left alone all weekend in a big house will invariably engage in lesbian sex. And when little sis complains about being left out, she is immediately introduced to every sex act imaginable. If you're a single male, visiting married friends will involve your fucking the wife while the husband fucks you because, you know, it just feels right.
