Friends?

I have a friend (male) who I have known since third grade. We have always been pretty rough with each other but about two days ago it kind of changed. Instead of the usual wrestling that we do we both got really into it. We were both hot and sweaty and my legs were around his waist and he was grinding against me. He flipped me over and did the same thing to my ass. I was was stunned for a minute I didn't know what to do. I was enjoying it and getting really wet but I knew it would have to end because we are best friends and sex would mess everything up. He would be taking my virginty, and I would probably become attached which is not a good thing when it comes to him, because he is somewhat of a player. I jumped up and said something about having to go to practice and ran out to my car. I hope I did the right thing he hasn't called me since.
