My husband won't do what I ask in the bedroom 😥

I am currently 32 weeks pregnant, so that doesn't help, but this was happening long before I got pregnant. When my husband and I first got together, I thought he was amazing in bed. Never before had I been with a guy who would just grab me and basically attack my body (in a good way) and it made me feel so desired! He was the first guy to ever make me orgasm without my help, too. Well, after awhile I figured out that he basically had one formula that had worked for him and he used it over and over and over again. He kisses me passionately, then he vigorously rubs my clit and/or eats me out with a lot of fast and forceful tongue movements, then he usually gets into missionary and goes hard and fast until he cums (but he used to make sure I always came, too). Sometimes he will throw a little doggy-style in there. It's great sex when I am in the mood for some athletic, energetic sex, but I want different things at different times. We have been together almost five years now, and I have had MANY conversations with him at this point. I have been gentle and kind, and I have also been harsh and straight forward. I have made specific requests before, during, and after sex and had them all ignored. I have physically grabbed him and tried to move him the way I want to be touched, and have shown him how I like toys to be used on me, and he STILL just reverts back to the same motions every time! I have also tried not letting him touch me at all while I do my best to please him, which he enjoys but then never returns the favor. I know he really likes foreplay and slow, gentle stuff done to him, but he won't do it to me! Now that I am super pregnant, missionary is super uncomfortable for me and I have told him multiple times. Plus, everything down there is so sensitive that it actually hurts when he is too forceful. The last time we had sex I didn't enjoy it at all because I had to keep asking him to stop, kept grabbing his hands, and then had to forcefully lift him off of my belly when he went for missionary again. I just don't get it! Why does he do things that are clearly for pleasing me, not him, like fingering me, but then ignore me when I say "Hey, can you go slower please?" I would really like to enjoy sex with him before I can't have any for awhile but now I just dread the next half hour whenever he starts the "we're gonna have sex" kissing. Help! 😥😭
