Sexually frustrated to the max

So I’m 17weeks pregnant and my sex drive is in the toilet. More so than usual because I suffer from depression that can be harsh on my sex drive anyways. Usually once every 2 or 3 days, whether I’m in the mood or not, I’ll have sex with my husband or we’ll fool around because I know it’s important in a marriage to fulfill your partner that way. However, since being pregnant, I just CANT, it’s uncomfortable and I just get irritated because he doesn’t care if I’m in the mood or not as long as he gets his. And maybe that’s my fault??

Anyways, we’ve been getting into it and I brought up to him that I don’t get anything out of it anyways (ORGASMS) he’s never once, even in 5 years of marriage, made me finish and we’re on our second kid together. We’ve tried toys, lubes, positions, games, kinks, etc. I’m pretty straight forward about what I do/don’t like too. We’re both sexually frustrated but in completely different ways and I don’t know what to do. Do I have the right to say no for days on end because I just don’t want to? I feel guilty- but my husband is a “sex 3 times a day” kinda guy and it’s EXHAUSTING. HELP.
