Sex drive GONE 😭

We are on the road together 24/7 but we have had this issue for about a year or so now. When he got close to 30 his drive slowed down a lot. Now that he is 30 it has pretty much completely stopped and we really only have guilt sex now because I get so frustrated he gives in just to make me happy for a while. We just talked tonight because quite frankly I feel disgusting, unattractive and unwanted and he said that "he doesnt have time to himself and that he just enjoys me being able to be here with him" and that his drive just isn't what it used to be. I understand him completely but my drive is really high and his non existent really gets to me. Its a constantly struggle of feeling guilty for wanting him and then feeling disgusting in my own body. I really wish I knew the answer. I love this man more than anything but I'm struggling very hard being rejected sexually and not being wanted.
