I've read a little bit about his story. I don't know what he can do next, but I see they are working and trying to change things.I have the slight suspicion you don't know his story...
If they know how and when things work is that good enough for him? Can he be satisfied? Because we all can be asking others what's normal or not in their relationship but that may not be normal in our relationship and that's ok! We are individuals after all.
9 minutes seem quick? According to what? Who cares about the time as long as they are satisfied, but I think he feels something is not right?
