Always a market, everyone is someones type

Personally I prefer them as sissified as possible, just something about them drives me wild

Some Doms want a relationship outside of the scenes and some don't, it depends on them

I agree with TheBookCollector

Thats a *** that can be on both sides, the *** of loss is very common in the beginning, and while often its unfounded its mostly the doubt in our heads talking

Then tell him that you don't want to be left alone afterwards, say that you want him to be there because you need him for support. He might change

It sounds like he may be using you or that he is trying to give you time to recoup after each scene however, that is may not the case. Have you asked him about it? Communication between D&s is critical.
