What does my friends with benefits want and why won’t he tell me?

Okay so I’ve been seeing a guy, kinda like friends with benefits, for about a year now. He has become more affectionate lately and I’m not sure why. Why would he kiss me on the forehead when I’m sleeping and then leave me in bed, go to the gym, then come back to me and say he didn’t wanna wake me? Another thing is I’ve noticed that he is basically making love to me now and not just having sex, he has been looking me in the eye, is he making love? He also like never has me go down on him, but ALWAYS goes down on me and now he has started kissing my kitty, what the heck does that mean? He has made it clear we aren’t in a relationship, but gets jealous and angry when any exes try to message me or start issues in my life. Please tell me what the heck is going on and how I should be perceiving this?
