Very frustrating.
I am in control and in charge, by necessity, of everything in my life. When I get into the bedroom I am all about pleasing. He gets off, I get off because he did. There's more to it. I didn't decide to be a submissive, I just have a word for my feelings now. I am capable of dominence, but I don't enjoy it.
I imagine a dominant could feel the same way. The dom/domme needs this, it fulfills them, satisfies them more than anything else. I'm new to all of this, I don't claim to know the mind of a Dominant, but just some thoughts.
