thank you all for your comments.

Master Saintans definition made perfect sense to me and i think that with this definition i will be able to utilize when going through the next few weeks of discussions and limits.

anyone have any suggestions on how to communicate these ideas either before an agreement between Dominant and submissive is made and also during a scene.

firefly brought up the point ...

i think there is a clear difference in BDSM terms; a submissive has more rights of negotiation than a slave, (just for an example –i’m sure there are plenty more situations-,) a submissive can refuse to play if he/she isn’t in the mood,
how would you do this?
