I just need to vent about my sex life

My boyfriend always gets REALLY hard in his sleep, and sometimes I'll notice when I'm up late and watching tv, or sometimes I'll see it throbbing and it turns me on sooo much. I want to wake him up to have sex literally everytime, but he's such an angry/ grumpy sleeper. And he makes having sex seem like a chore sometimes so I feel embarrassed to even try most of the time because he'll reject me. And I've thought about/ tried masturbating to make me feel not so anxious, but it's not the same and not nearly as satisfying. Even with sex toys, it's still not good enough for me. Anyway, we used to have sex like 2-4 times a day, and he used to wake me up in the middle of the night by going down on me or just by kissing me to have sex. Now it's like his sex drive is MIA most of the time, and he has to "give in" and I hate that so much. It makes me feel weird, like I'm making him do something he doesn't want to and then it frustrates me because I want to have sex but then I feel bad about it so I don't. I don't know what to do to make him want to have sex like we used to. I feel like I don't turn him on as much anymore, and he'll called me a nympho because I get moody when I don't get dicked down. But I don't want to have sex with anyone else, we've tried dating other people before and I know it doesn't work with anyone else, the thought of it makes me sick. I don't enjoy toys, I just enjoy him. And only him. I've given up on buying lingerie and getting sexy for him because he doesn't seem to care or notice. Like, is something wrong with me? I'm attractive, interesting, I can cook, I clean, I take care of him and all his needs after he gets home from work, I treat him like a king. I just don't get it. We don't live together, but we spend a lot of time together, sometimes I stay with him for a week or two, but we still give eachother space then. Someone please explain.
