Confusing situation friend/bf?

I’ve been friends with this guy for almost 2 years and I know the entire time we’ve been friends he’s liked me more than that.

We’ve been speaking a lot more recently and started having sex- it just happened in the heat of the moment and it was SO good and keeps happening. We see eachother like 3/4 times a week now and go out to do things to but I’m scared that I’ll lose a friend if this doesn’t go anywhere and I’m super confused!!!

I could really use some advice???
