Just to be clear, I think some people are okay with a sexless marriage, they are not tortured by it. If they are okay with it and find peace, then I have no issue with the dynamic at all. I only get fired up when one partner is deeply dissatisfied with their sex life and the other partner chooses to say "too bad". That seems to be your sitch, and I don't understand how you can find that maintainable.
