Me and my best friend... Were becoming more...?

okay... so my best friend is a guy named Edgar. a friday night we were in my room just chillin and he took my cell phone. he was tryin to read my messages (since i was so caught up in my texts). so he wouldn't return my phone. he was on the ground and i was on my bed. so i went and i was tryin to get it back. on the midst of it all we ended up kissing... then it led to a make out. a couple days later he wrote me on myspace tellin me that we should stop, cause it was weird with us bein best friends and all. a few days ago we were at his house and no one but us was there. we were on the couch and he kept gettin closer. then he just asked "remeber what we did the other day? wanna do it again?" so we started makin out, then we went to his room. he kept tryin to get farther. but he didn't, just a make out. help!! i dunno what to do!! im experienced (not a v) and he isn't!! help!!
