Insatiable help

My bf and I live in different cities so we only see each other once a week or once every two weeks. When we meet I am very horny and always want to have sex but he can’t keep up. For example this week end we were together from Friday night to Sunday afternoon and we only fucked once a day and today he did it only because I was pouting.

I feel very frustrated because I need more and he just had enough.

The thing is that we don’t do vaginal because I have a sort of blockage that I need to fix. And I only orgasm with anal which I love.

Is my situation normal? How can I stop this frustration? We are both 29
