I hadn't really thought of the dynamic until now. I think it's more...something ingrained.
First of all, I think most of domination and submission is psychological. There is a big difference between being a submissive and being a masochist. Or being a pain slut. Not that there is anything wrong with it, but I find it hugely more erotic to focus on the big head. I think of it as elegant. Elegant in that its refined and there is some dignity and it's beyond exciting. When it plays out correctly.
As girls, and I don't know if this is something unique to my family, or the South, or just old ways, we were reared with certain manners and customs. We were taught certain things about interacting with boys and men...oh so many. We were taught this from as early as I can remember. That is why it is ingrained. It's not that I'm not strong and independent. I know I am. But my mom taught me how to play the game.
When you go on a date, she said, act as if you don't even know HOW to open a door. If he doesn't get it, just wait quietly by the car door. He will come over and open it for you.
Do you know what that is? That is allowing the male to be dominant. When a man opens a door for you, or pulls a chair out for you, or waves your car through a four-way stop, he's not just being polite. He's telling you what to do. And by graciously and wordlessly...and thankfully...following his direction, you are allowing him to have control. You are allowing him to be the man.
But you are controlling it. I can open my own doors. I have physical (and emotional) strength that many don't have. He may not know it, and you innately know it, and you ALLOW it to happen because...because we like it

Because it calls to some very primitive part of us that responds to the Alpha.
Being dominant in a way, it's a form of weakness...and I say that without judgment. I had a boyfriend for years who NEEDED to be the one to drive. I can drive or let him drive, and be okay with it. So who is the stronger? He was dominant without even knowing it, but I knew it. If he playfully spanked me, I could tell he really liked it. He gave my order to the waiter, I kept my eyes on him. You know, it was like that. I could make a list as long as my arm. I don't think in a million years he would have suspected what I was doing, what I had been taught to do, and how gratifying it was to me to please him. I think he had no idea how gratifying it was to me when he was the man. And the sex was amazing.
And conversely, when he observed me in a position of power, for example, in my work life, he had a very hard time dealing with it. He needed to feel on top. He would become angry, withdraw. And probably impotent, even, who can say? I got punished in subtle and not so subtle ways. It was only when I resumed the role he liked that he felt drawn to me again. But that was his weakness, not mine. Never would I have done the same to him. I didn't feel the need to. But I was strong enough to be what he wanted. Maybe not strong enough to walk away. That took years.
There are rules...but they are unspoken. I recognize the vulnerability in the man, and I would never, never betray that, or emasculate him, as other women may have done, as I see other women do, in so many subtle and unkind ways. It is my job as a provider to let him be the man.
Southern women are taught that their husbands are their religion. But we also know who holds the real power. Even gods need someone to worship them. Maybe that comes into it.
So that is why I say submissives wield the power and if we are smart, we never let them know it.
I think you see this elegant submission played out in a funny -- but very real! -- way between Morticia and Gomez. Can there be any question who is truly enslaved in this relationship?
