Well, girls mostly. Unless you swing the other way.

I can't really say I know a lot of girls that fuck around , nor can I say I know a lot of girls, but I DO know a couple of guys that go out every Thursday, and succeed to get their fingers wet - and the amazing thing is, they never get together with the same girl. They've been doing this every Thursday for the past 3 years, or so, and it's always a different girl.

How's that for fucking around?

Ooooh! Slipped my mind - I know of at least ONE high-class hooker.
