This is not relevant to anyone else, but for me personally, I can't even stand the thought of being punished in any way - physically, verbally, anything. Even in play I don't like punishment. If I would disappoint my partner I would want him to discuss it with me, period. Just knowing that I had disappointed him would be sufficient punishment, without any scolding or anything else, and I would be highly motivated to do better in the future. If I were punished - I think I would just shut down.
