Not a physical person?.

I have trouble with my fiancé because constantly wants to touch or have sex with me. I am not the type of person that being physical is at the top of my list. I feel bad because it makes him feel I am not attracted to him at all, which I am! He is the sexiest man alive as far as I’m concerned 😍😍 I’m just not in the mood as much as him. Anyone else have this problem? Is there a solution to my problem 😩 I feel like a failure 😢
