lostgame...you scare me. You're 17 and you've been doing it REGULARILY?
you DO appear to care about the girl, and you don't appear to do it for kicks, which is really something for a minor, but I just think that it's wrong. then again, it's you're life, I can't tell you how to live it.
I think it's wrong because...you could really end up hurting someone. I mean, if you get laid with a woman, (and let's say the condom fails) then if dump her, she has a horrible decision to make. bear the child and raise it by herself, or abort, and live with that for the rest of your life.
and it think it's ESPECIALLY bad for minors. I mean, most kids these days who are sex maniacs have NO friggen clue WTF they're getting into. Most just see it as a fun thing to do, and don't care about the consequenses (lostgame seems to be a rare exception).
