What, more than anything, really gets you off?

Is there a toy that's just amazing? Is there a scenario that revs you up? Is there a video or a story you find yourself going back to? Is it a specific quality in a partner? Whatever it is, missionary with the lights off, being tied up, immobile, and used, anything.
