I am a very sexual top, and me and my partner have been together for a year and a half. In the beginning he seemed to be a happy bottom, but more and more he has wanted to top me. I really hate this but I have done it for him because I love him. He says he still loves me toping him but it really doesn't feel like it. He normally is limp when I top him. I feel more and more empty each and every time we have sex. I don't want to leave but I feel like we are at a dead end. What should I do?
