Sex in pregnancy

I hear a lot of women struggling with low libido but my problem is my partner's. It's not about "being scared to hit the baby" or not finding me attractive, I think it's the whole concept that I'm carrying a human that's killed his libido. We talk very openly, we've analysed this from every angle... but it's getting from infrequent to...nothing. I'm getting fed up and while I know that it'd not his fault and not something he chooses to do, it's making me resentful. Anyone else struggling with the same problem?(I don't think this is sensitive content...we're all pregnant anyway😂!)
