Well, this is loaded series of questions because I don’t know the dynamic but I see two things here: (a) a series of what seem to me to be legitimate D/s relationship things (i.e. orgasm denial and begging, establishing his role, when to use pet names, etc), meaning he doesn’t seem like he is asking for horrific shit I see from a lot of other Asks, and (b) the fact that you are asking me, not him, implies a disconnect in your communication.
I suggest if you are seeking a D/s relationship with him, that you and he make sure you are on the same page with your communication.
Have talks out of your D/s roles, maybe look into submissive journaling, and more ways to make sure your questions are addressed so that you and he both know your expectations. I suggest doing that well before you have sex, but it sounds like you may be playing catch up now, so just try and correct your communication disconnects and you will be fine.
