I think a sub can in fact drive a Dom to that point. In fact, I know they can. It's in the nature of the relationship. Sure, you can take her any time you please, but thats not what you needed. You needed emotional release far more than physical release. Your mind was full of thoughts, and all that needed to be cleared away.

I'll assume you did finally take her, and you both felt better for it. And you probably felt much better, for having let her pamper you much longer.
