Sex😊

I rarely reach the big O with my husband. I mean we have been together for 7 years and I can count on both hands. He is the only person I've been with and I find him extremely attractive. I'm I the only one??? Or is it normal. Idk what to do I've never told him because he would be heartbroken. He takes it as that I'm not attracted to him and he gets angry if I don't. After getting frustrated I just give in a fake it to get it over with and make him feel accomplished. I know it's wrong and that why I'll most likely never but I can't hurt him because I know it would. What would you do?
