From just friends to sex....help!!! How can I fix it?

You need to take two steps back a breathe! I feel you are hurrying a decision for him that is going to end bad. He is just as confused about the situation as you are, and the way he is dealing with it is space. Give it to him. The more you try and pressure a 'forget what happened and move on' type feel, the more he will push you away. He might be scared that because of what happened, that now you want to be his girlfriend. Which as you mentioned you don't, but does he know that? My advise is give a little space to him, then talk like adults about it and realize y'all feel the same way about the boyfriend / girlfriend topic. Next thing you know you are back to the way you were, with maybe gaining a friends with benefits on the side =).

Well if you never had strong feelings 4 him you shud not have done it. He jus used you 4 yo body. Once he get what he want he done.

I've been told that you shouldn't have sex with your friends, for just that reason, things will never be the same. I am not saying that your situation can't be fixed, I'm simply saying it won't be the same. I know a person, who had been friends with this other person for a very long time, they decided they were going to explore, (ya know, play house), so they started kissing, it felt awkward, so they tried it again, a long sensual kiss, and when they finished they looked at one another, and laughed, and laughed, because they knew after that last kiss, that they were friends ONLY nothing more nothing less. I'm assuming you went farther than the kiss, and now things are really awkward, well, you have done your part, the ball is in his court. Let him text you, and when you are on myspace, and you see he is online, sign out. If you can fix your page where he can't see ur online, that would be even better, (for a while) he'll wonder why you haven't been online, why you haven't texted him. Give the guy some space, maybe he doesn't know how to take what happened between the two of you. Just learn from it, give him some space, and keep on doing what you do. He knows how to get in touch with you.
