My T has told me that he would honor my wishes, even if he didn't like or agree with them. I also know that my T doesn't like playing guessing games. If I want or need something, I have to ask for it. It certainly helps me learn how to be more direct, which is beneficial in relationships as well....any-hoo...I'd imagine that it would be ethically appropriate for a T not to call you if you asked not to be called.
