<human>: Give me the gist of the text in a nutshell

I've (21F) been with my boyfriend (26M) for two years. We've lived together for a year now. We have ups and downs but we love each other and he is probably my best friend.
The issue is our sex life. For one, he isn't a generous lover. He never really goes out of his way to please me. It seems like I'm always the one in charge of whether or not I get off. Or I basically feel like I'm begging him to make the extra effort to get me off. I go down on him usually every time we have sex and I have basically worked hard to make sure I can give him the best head of his life. He has gone down on me five times in our entire relationship.. He has jaw issues and says it irritates his jaw. So I'm not sure if it's fair for me to ask he does it.. But I wouldn't mind it so much if it at least felt like he wanted me to reach climax when we had sex. 
Another issue is our schedules. I enjoy sex at night but I'm pretty flexible. He likes it during the day. I work days so usually that isn't an option. Normally he will just take care of himself during the days and then we will only have sex once or twice a week. This isn't enough for me, especially if I'm not climaxing each time. I've tried different ways to try to get him in the mood at night but it usually doesn't work. Getting turned down for sex so much makes me feel awful about myself and makes me feel nervous to try anything else in fear of getting turned down again. I'm really not unattractive or out of shape, I get lots of compliments about my looks.
I've tried talking to him about these issues and asking if he has any fantasies he would want to try to get him more excited about our sex life. I feel like I've tried it all but the only thing that works is just whether or not he feels like it. It just feels like he is very lazy in all aspects of our sex life and it's so frustrating when I'm putting in lots of work to try and make it better. I don't know what to do.
