Redpepper, thank you for going out on a limb.
I simply want to underscore something that has been mentioned over and over about D/s that a lot of people seem to fail to realize:
It supposed to be all about feeling GOOD. The Dominant feels good pleasing the submissive, and the sub feels GOOD by pleasing the Dom. It is NOT about the Dom "expanding" the sub's boundaries by making him or her do things they are not ready to do or wouldn't normally want to do (unless this is ASKED FOR and AGREED TO without emotional blackmail).
