slut lock

Woman asks:

If I sleep with 3 men, everyone calls me a slut.

But when a man sleeps with 8 girls, everyone calls him a real man.

How come?

Confucius replies:

It's very simple. When one lock can be opened by 3 different keys, it's a bad lock.

But when one key can open 8 different locks, we call it a master key.
