Your marriage is sexless. Your vacation is sexless. Your life is sexless. It doesn't have to be this way though. You can try couples therapy but that's so costly and takes too much time. Why not try chastity? Maybe some cuckolding? There's always a chance you won't like something you try but there's a higher chance that you will love it. What if she loves it? What if she loves both? It's worth the try. Otherwise things will continue to stay sexless for you both. She hasn't lost interest in cock, only yours. How hard do you think she can cum for one she doesn't know?
