Requisite disclaimer: i only presume to speak for myself, i know we all vary.
When i was younger i read the Carlos Castaneda books about the sorcerer Don Juan. At one point Carlos was trying to see the spiritual (paraphrasing from memory) and it kept alluding him. When he queried Don Juan as to why, Don Juan explained that the spiritual cannot be seen by directly staring, but can only be seen peripherally.
i read that 40 years ago, but it stuck with me, i find it applies to a lot, and today i saw it in the context of power exchange. When a Top/Dom/Man is a little unsure of Himself, wanting/needing/asking for control, my wiring, the bottom/sub/? in me opens wide and craves to give Him what He lusts for. But when He tastes my response of submission, takes it for granted, presumes it, i shut down. Sure, i can play the game, follow the rules and 'submit,' but He has lost me, He just retains the appearance of submission, control.
If He does not presume to fully grasp His power, if He gazes at it peripherally, He retains control and wholly possesses me.
