Sleeping with a friend...

So today I came home from spending the night with a guy that I have been on a few dates with but is still my friend none the less.  I had sex with him and he hasn't really said anything about that situation. I don't know how to feel about him and I know he isn't good at expressing his emotions so what should I do now? Should I be expecting him to ask me to be his girlfriend or not? I need some advice. Sorry in advance for being so lame it's just I haven't been in the dating game for a while
