Such a joke. It's not true that all women sleep with 10% of all men. Maybe it's that the women who want to have casual sex sleep with the top 10% of men who want to have casual sex. But most women don't want to have casual sex. And if it was true that only 10% of men sleep with all women, you'd see harems and 90% of men would never have a relationship. But that's blatantly not true.

That being said, self esteem is great. And just because you got rejected by women when you were trying to cold-pick them up doesn't mean they would never sleep with you in other contexts. Most women will never agree to sex the same day they meet you. Or the first few days they know you.
