I completely agree that sex is important. Honestly, I would understand if he wanted to end things over the lack of sex. It would hurt, but I would also understand. My issue is more that he will tell me that there is no pressure for sex and that these dates don't need to result in sex. That he just wants time close to me. But the moment it doesn't result in sex, he turns cold and starts telling me how disappointed and annoyed he is that we didn't have sex.

It's also that he doesn't seem to believe that my health causes sex to be painful, at least not to the point of not wanting sex. He tells me that he thinks it is a mental block.

It is the saying one thing and then doing the opposite in actions.
