Wilt Chamberlain
claims to have slept with 20,000 different women in his life.
According to close friends, Wilt loved threesomes. According to legend, he was intimate with 23 different women on one 10-day road trip.

In the future perhaps the nature of our culture will make it macho-positive for Hero personalities to tell us how many notches on their bed post were male and how many female.
