Another headcanon of mine is: Crowley and Aziraphale both know that the angel likes to play the damsel in distress sometimes, that he likes Crowley to know what he wants without actually saying it out loud.
So. Having Crowley play the dominant part from time to time means, that he'll have to swallow his pride and tell the demon word for word what he wants. And he can be sure that he'll get exactly what he's asking for.
