Obviously (from my participation here) I'm neither female nor a submissive, but have been here long enough to answer. Both my own perception and that of many others who have responded before to this very question.

It all comes down to exactly your definition. Equal rights. You have the right to choose how you live your life. You're choosing to submit. As long as you hold to that, that you are making the choice and not being coerced by anyone, outside of yourself, you can live with both your submission and your feminism.
