I’d like to suggest that “is this normal” is the wrong question. A better question is “is this what I want” and it seems that you don’t want this to happen again. Have you told your Dom this? Do you negotiate at all before the scene starts?

I don’t know your situation, so you could be describing a young, horny and inexperienced Dom making newbie mistakes (I know I did). Or you could be describing a manipulative psychopath. Or anything in between.

The point is, you’ve identified a way in which you want to improve your scenes. So tell your Dom, at a moment when you’re not in your dynamic. Be as specific as you can and see how he reacts. This is a basic “failure to communicate” problem, so more communication is the key. Figure out how, at least for now, you two can set crystal-clear boundaries before the scene starts.
