That was worded in a really confusing way. I think what you're saying is that you had some sexual contact with this person, which because of your age is illegal in most states, correct? (Not in Canada though)

I thought people weren't supposed to talk about illegal things on this board. Everyone who offers advice is putting themselves in a bad position..don't you think?

Anyway, since I'm a woman, and can do no wrong, I would say that if something wrong and horrible and illegal happened, then go to the police. But if nothing happened that was horrible or forced, or whatever, then leave it alone. I don't see the point of asking the question, because it sounds like you already know what your feelings are. It makes me question the whole truth of the post...
