Not feeling wanted

I’m 34 weeks pregnant and me and my boyfriend basically have sex once every blue moon now I mean I’m literally begging all the time. I mean we been together for going on four years and this is our second child together I think I try to have sex more for his needs then mind cuz when I’m with someone I love them and the sex never been great cuz it’s so basic and his belly always in the way where it limits us a lot 🤦🏽‍♀️ I just hate feeling unwanted while pregnant...
