How to feel sexy while pregnant ???

My husband and I have always had a very healthy sex life.. Now that im bigger everyday sex is getting more and more uncomfortable for me. He is very understanding and we've found positions that I don't feel like I'm dying in 😂 But the bigger I get the less sexy I feel, I think because I'm not as limber and energetic as I was before. He thinks I'm more and more sexy the more pregnant I get. I still 'want' sex, but my lack in confidence is hurting our sex life. Is this normal? Any tips to feel more in the mood?
