Big and pregnant and not feeling even pretty

I don’t feel pretty or hot or anything and my boyfriend doesn’t really help. I mean he calls me beautiful all the time but I don’t feel it. I feel as if he’s not attracted to me anymore because I’m 8 months pregnant. And I keep making the excuse that he works nights and he’s just really tired but when we do have sex it feels like he rushes to get me off and he doesn’t last long at all. He never ask for sex anymore and he doesn’t even rub up on me like he used to. Like I get that you know an 8 month pregnant body isn’t the greatest thing and isn’t the most sexually appealing but I don’t know how to talk to him about this because all he’s just going to say is but “baby I love you you know that” just typical man replies and I just wanna feel like I’m still the same person to him I was before I got pregnant.
