Well--those kinds of relationships make me anxious, because ideally people shouldn't ever feel coerced, and dodgy power dynamics are especially dodgy on the consent/coercion front. This is why I really prefer what's almost a subversion of the trope: the person who we might ordinarily consider the 'powerless' one gets to call the shots. That form of the dynamic rests more easily with me.

But, all that said, I can't seem to stay away from exactly the relationship you wrote. Maybe that should bother me. >_>;;;
