In my case it is anal but sometimes it can be other stuff that I'm really in the mood for. Sometimes we (LTR) are having normal sex and I do, or tell I want to do something else, and get a hard, unsexy, no.

My initial response is to get bummed and lose interest. The thing is that I'm not sure with myself if it a good or bad reaction - If this is a blue-pill pouting or that I know the sex will not be as satisfying to me without the thing I want that I walk away entirely. In the past I used to do more things that I know she likes, the sure things, and to give up on the things I wanted, so the walking away seems somewhat of a progress to me.

Now I know that in this specific case, anal sex is something that requires some endurance on her part, since it can hurt or be unpleasant sometimes. She says herself that if I want' it I should initiate it when she has more energy and not, for example, before we go to sleep. But I enjoy banging her in the ass so much that it comes up every second or third time. Sometimes she agrees and sometimes she doesn't.

How would you handle this situation?
