Sex drive?

I love my husband I do. I feel like I have barely any sex drive and he wants to have sex almost everyday but I honestly want to cry when I feel like I owe it to him because I don't have a sex drive and he'd never make me do anything I don't want to. I don't know what my problem is or if it's just normal wanting to just spend time with him he also loves spending time with me but at the end of the night I just don't want to and I am attracted to him I think he is so handsome. Am I alone on this one?
