[NSFW] What do you do that makes you feel powerful during sex? [See details]?

I don’t know if others feel this way, but the feeling of having someone want me so badly they’ll do anything, sexually speaking, to please me really enhances my experience. I’ve heard others talk about how doing this act or that one makes them feel powerful and they indicate that this power is highly arousing or satisfying all on its own.

My question is not just the question in the title (what specific acts make you feel powerful). That just starts it. The real question is how does that act make you feel powerful and what is the invisible train of thought that runs through your mind when you are doing it (or having it done to you)?

To put it another way, what is the story you tell yourself about what is happening when you feel this power? What are the associations you have with that scenario? What gives it meaning for you (aside from the pleasure it provides). Or what meaning does it provide that makes it so much more pleasurable that other things you might do?
