I think discipline can act as a relief for stress and guilt. Not for everyone who likes bdsm but for a significant number.

Corporal punishment and a pink chastity cage have made me the cuck I am today. Early on in our journey I would rebel and be disrespectful to my wife and our bbc bull, but thanks to a bamboo switch applied to liberally to my backside I learned to submit to black cock superiority and white female authority.
