One more perspective to toss out into the mix...

Our sexual personalities depend on more than just who we are inside our own heads and desires: we also have partners. The triggers they trip for us blend into our natural state of being and create "us" within that relationship. With J, I am very submissive. I have no desire to Domme him other than in a flip and playful manner. This being said, he's one of a very SMALL number of people that has ever drawn that out of me. My inclination with most men is to top the situation and be in control. Does that mean I'm confused? Or perhaps a switch? Nah, for me it simply means that my "inner Domme" is there to protect my true submissive self, and (I've found lately) to care for and protect others. The deep "truth of me" is sub, however and it takes a particular person to draw that out.

Debate, discuss, I'm off to grab a cookie...
