Bad sex

So, I have found that the guy I'm with and I have bad sex. And it has nothing to do with attraction, because when we aren't actually having sex, I want to be. It's just that it doesn't feel good to me and by the end I just want it to be over. Tonight, when we finished, I wanted to cry because I didn't understand what was happening and if we should end things because of it. Well after some searching I realized that it wasn't incompatibility, or that he wasn't trying he's just inexperienced af. My question is how do I deal with this as I am also inexperienced. What should I do about this? Any advice. (I tried spicing it up...but that just got him too excited and rushed the entire process and we once again started before I was really ready).
