It all comes to hypocrisy

I know almost no male that doesn't want to score a dozen different people (women, men, girls, whatever rocks their specific boat) everyday.

But the majority of them also want to be the only one with the privilege. They want everyone of their desired partners to be easy for them and hard or impossible for everyone else.

Which is how, depending with which set of organs they are thinking, they defend either sexual freedom or sexual repression.
