Pregnant, plus sized, and doesn't feel sexy

I feel like over the years of being with my now husband, I have lost my "sex appeal".

I gained weight, stopped wearing matching underwear, barely ever shave or do my hair, keep my makeup at the bare minimum. Every now and then, I step it back up but I'm just not that person anymore. Basically I stopped "trying".

In the past few months, our sex life has gone dramatically downhill. He swears he loves me and there is nothing wrong, blamed it on the pregnancy for a bit then took it back - but I can feel it may have to do with me "letting myself go" and I'm terrified to ask him about it directly because I'm honestly scared of hearing him say everything I feel back to me. It will hurt so much.

So my question is... how do I get "it" back? How can I turn my man on again? How will I get him to be so into me like he was before? I miss having sex, and getting compliments, and having him show me off. I am grateful for the emotional affection but I liked the physical stuff too :(
