Hmmm. I agree that one sentence is hard. Our natures are Dom/sub, but we are also boss/employee, but aside from all that are equals. He appreciates my intelligence as much as my wantonness, and while he likes to control me on a physical level, would never, ever attempt to control me mentally. That makes him perfect, in my eyes. He is demanding, generous, a perfectionist, sporty, skilled with his hands (in sexual and non-sexual ways!) and loves a good negotiation. I've joked to him that if he had me mentally under his control he'd lose interest, because he loves a battle!
