Theres an old saying. Well, maybe not that old. It says "You can't rape the willing." It may sound funny, actually, it is, but its sort-of true. For instance, you can't rape someone who says "F%$# ME!" (I'm thinking of @ the beginning of Scary Movie 2 where the priests are in the girls room and the father starts humping her!) So, if you were just the tiniest bit willing,(for instance, you had an erection), then it wasn't really rape, was it? I mean, if you whip it out, and the woman's nipples get hard, is it rape? You case is very confusing. However, if she is older than you, (Like she was 19, but you were 17 at the time), then it is molestation, because you were a minor, and she was an adult. Do you still like the girl? Do you know where she lives? It was about 2 years ago, so it would be almost impossible to prove rape. I think you should talk to someone about it. Then move on. You can't change the past, unless you have undying evidence/proof.
