Super high sex drive while pregnant but asexual husband....

My husband is asexual but we still do have sex time to time. He made very strict boundaries when we started dating when it came to sex. This is what he will do. This is what he won't do. I try really hard not to cross boundaries. We've actually made our relationship work really well. The only issues we've ever had was sex and with understanding boundaries and compromise, we made it work out. Well now that I'm pregnant my sex drive is through the rough. He hasn't been able to meet those needs. He does masturbate. Not much. Maybe 2x a month but when I find out he's masturbated instead of having sex I feel hurt and he said he was just doing it to get it over with. I'm still learning new things about asexuality and I did find out a lot of asexuals do masturbate. Before anyone says anything no he's not a porn addict. I watch porn but it does nothing for him. I tried to sit him down and ask if we could compromise and have sex more often but he flat out said no. And he has boundaries and I have to respect them pregnant or not. Sexual frustration and pregnancy suck so much.

I had a very traumatic experience with sex toys as a child. So they just bring trauma.

I definitely probably should have gotten therapy after what happened and have been thinking about it
