I doubt I'm switch, I need to be in control of everything and if I can't be in control then I will fight until I have it. Rite now what I really want is to be sub for a sadist dom not afraid to push limits who is just as extreme as me or more so.
As far as what role you are that's all how you feel.. whether you need to be in control, please others, or what goes around comes around. The only way to tell for sure though I'd say is to try both roles.
