I feel so unsexy!!!

So last night I FINALLY talked my husband into having sex with me. It's sad we literally have not touched for months! Since I started showing! So I got on top and he looked so miserable so we had to switch to doggy style so he could finish. He apologized and said the belly just throws him off. I feel so rejected and disgusting... I don't know what to do because my sex strive is extreme. Anyone have any advice?
