sex during pregnancy 😬

This may be TMI but I'm 23 +3 & about a month ago, every time we have sex it feels like a UTI on steroids. Literally. I'm in so much pain after & for a few days following. I also cramp ALOT after. He's become this cry baby brat that thinks I'm saying no out of spite just to be mean. He says it has nothing to do with the pregnancy that I just don't want anything to do with him anymore.  No my sex drive hasn't come back yet but I was going along with it for him before this started happening. But now I don't feel like I should suffer in pain just so he'll be happy & shut up.
