Yes.
Tell him then he should make an effort to be careful.
I think you should. If I've been talking to this guy for a while, and we want to hook up, i would want to know if this guy is a virgin or not.
yes
There is no physical way to tell.
Yes
You should tell him
you should ask a friend to tell the guy that you like him or you should go up to him and tell that you like him.(because i did that with my crush)
Yes
yeah he probably will like you..:) Yes, but what kind of a friend would spill such a private secret to anyone else? In my humble opinion, that is something you should have the right to tell, not your "friend".
If you don't tell him, he has no chance to respond. But, nobody here knows you or him, so it has to be your decision.
You should do that.
Tell him that you really like him.
