Recently, I've been mulling over the concept of female supremacy. While I very much enjoy playing with the idea, I have come to the conclusion that I do not ascribe to the ideology per se. Rather, if there is any belief system underlying my style of domination, it would be that power roles cannot be defined by biology and should always remain fluid.
I embrace the femme domme/male sub dynamic for myself because I am dominant towards all my partners both male and female. Over and above my personal predilections, what I value about my work is how it turns convention on its head, thereby opening one up to the realization that alternative paths are possible.
I do not apply judgment to any of these roles. If I believed that only the dominant role were superior, then I would not respect the men and women who so generously submit to me.
Through my wealth of experience, personal insight and skills, I have a lot of confidence in being Mistress Xia. Yet I would hardly think the world would be a better-run place if all the men in charge were replaced by women. Certainly, it would be different. But to me, having one set of genitals versus another does not make one inherently superior.
