What are we? friends with benefits? does he care about me?

Ok I met this guy like two years ago and I always heard he had a slutty rep and had sex with tons of girls he's def a bad boy but back in the fall we started haning out and partying we hooked up in december and acted like nothing happened afterward and we still talked from time to time and parties so we hooked up again recently he's always told me he found me very attractive and sweet and not judgemental and friendly and he always opens up to me about family probs and different things in his life and he's always been sweet to me this last time we hooked up he went down on me and completely undressed me and most guys just trying to get it do just that nothing more ya know the next morning he told me to get back in bed just to lay there and then I had a friend text me yesterday and ask if the two of us were something yet but idk if we are just fu*k buddies or if he really cares about me if you think he cares about me then how do I find out
