There is no such thing. It is called masturbation and can be done at any time in a person's life.

I guess one could class it in with foreplay if that is part of it.

There is such a thing. Ive done it... just want to know what its called. Everything has a name nowadays, so someone's got to know. Anybody?? Somebody??

We've given you a name. While you are still a virgin (and after), it's called masturbation. While making love, it's called foreplay, like Fr_Chuck said.

What do you mean by "pre sex"?

How old are you?
