Having read the postings I felt a need to comment.
MoF, May I ask a simple question... Does your previous practices of BDSM, involve the Humiliation aspects, or were they one component of it? Degrading your willing supplicant, in a scene? Does that carry over into your private lives outside the bedroom?
Honestly, while reading this thread, I heard Robin Williams voice in my head, from Bicentennial Man, something about God's sense of humor putting pleasure centers so close to Waste removal...
