I don't believe in the concept of switch. If you are dominant, I don't know how you turn that off. If you are submissive, I don't know how you'd find it in yourself to dominate. Being dominant permeates all of your life from personal relationships, to work, to social interactions, not just the bedroom (or wherever you do what you do). On the other hand, wearing a costume or adopting a title isn't what makes that happen, either.
