Best friend? Boyfriend?

I’ve been best friends with this guy for like five years. A few months ago I got the suspicion he wanted something more, becoming more touchy and finding reasons to be alone with me. My suspicions were correct and we started fooling around recently we went all the way and had sex. However we haven’t broached the subject in conversation despite speaking everyday about everything else. I have no clue how he feels about me and to be honest I don’t know how I feel about him.
