I must admit that I too don't know some of the abreviations to certain words or phrases. Maybe this could be another discusion/thread.

Anyway back to the subject - If your a sub and want to be under total control and completely powerless, wouldn't 'YOU' choose that person to be the Dom because of trust and honesty and not just obediance and loyalty?
So a 'sub' does have an amount of control to perform the 'need' to be under total control. Does this make sense? Is this the white boards that you speak of?

Afterall, to achieve the 'lifestyle' that you want you have to organise, plan, comunicate and have all the trust and honesty between two people in order for this to work no matter how deep or different each others needs are.
