advice please

Ashley
So I'm 26 weeks pregnant and already very very uncomfortable. I can't wait to just have my baby and hold her and not feel like I'm carrying around a 10lb weight in my uterus.. (I can't even imagine how I'm going to feel at 36 weeks) but I feel really bad because my SO is literally the sweetest most caring guy and he does everything for me. Whatever I need he's right there to give it to me and I love him so much more for that. I've never been so loved before by anybody and it really just warms my heart. But I can't help but feel like I'm not giving him what he needs. He always wants to kiss and cuddle and make out and I just truly can't get into anything. Like my sex drive is at a negative and I feel horrible about it because it's nothing wrong with
Him. It's absolutely all me!! And I've told him that and he understands but I can't help but feel bad because he's so good to me and gives me everything I need and I want to be able to do the same for him. Any other ladies feeling this way?? Any advice??
