Christian is acting in a dom-y sort of way, which is fine. The problem is that Ana isn’t really into the Scene.
When he turns and gazes at me, his eyes are burning. I stand paralyzed like a complete zombie, my heart pounding, my blood pumping, not actually able to move a muscle. In my mind, all I can think is— this is for him—the thought repeating like a mantra over and over again.
Doing it “for him” is the problem. Ana is unaware of her own desires, or at least unable to express them. Again, she’s still thinking of this interactions in terms of “if I do what he wants, he will be nice to me”, instead of “what can he and I do that we will both enjoy?” It’s a recipe for slowly building up a reservoir of resentment.
