Sexually incompatible?

I (20F) have been with my boyfriend J (21F) for almost two years. He’s kind, funny and very smart. My only issues are that he’s not very romantic in the typical way and he doesn’t have a high libido. I am also his first girlfriend and sexual partner. There was a struggle in the beginning of the relationship with him staying hard during sex, which I assured him was okay since he’s never had it before, and that problem eventually went away. Our sex was good until it just sort of dropped off. Maybe we both got too busy with college, but out of the entire length of our relationship, we’ve only had sex maybe 20 times.
I was always the one trying to initiate sex and I found myself losing my self-esteem because I thought he just didn’t find me attractive anymore. We talked about it and he said self-esteem was also an issue for him. Again, I assured him that I was perfectly okay with that and I would help him every step of the way. However, now I feel there is a totally different issue and one that started creeping up on me a while ago. He doesn’t like receiving OR giving head, and there’s many things he refuses to do like degrade me because “he doesn’t want to be mean to me”. He also likes to dive straight into sex instead of starting with foreplay, and also barely flirts with me. After he graduated college, we have also became long distance which further decreases the amount of times we have sex since I only see him a few times a month. I tried to break up with him over this in the beginning of July but then we decided to keep trying. Fast forward to two weeks ago where we attempted sex but I just felt uncomfortable since he tried to go straight into penetration and I stopped him and went “we should do foreplay” and he was just very awkward with it. We talked again and the solution was breaking up or finding a sex therapist. He agreed to looking for a therapist but has not reached out to me whatsoever. I’m thinking about ending things again, but I feel awful. I don’t know if I’m too much for him, or if he isn’t just experienced enough for me. I’ve only had one sexual partner before him but felt super comfortable in that relationship during sex. What should I do???
