My wife is a very loving disciplinarian. Make no mistake that she is very strict with the hairbrush, the strap, and/or the bamboo stick! But, she doesn't try to humiliate me.
I don't feel humiliated. The word humiliation implies such a strong sense of disgust with oneself. If I deserve discipline, my wife certainly expects me to be humble/submissive, and accept my punishments. But she doesn't want me to feel like a total piece of shit.
My feelings of submissiveness are certainly enhanced by the ritual that my wife normally expects from me when I am to be chastised. She incorporates aspects of BOTH my required obedience to follow her instructions AND the expectation that I will passively accept whatever she does during preparations for spankings.
The question was which is more humiliating? Having to obey my wife's instructions to get naked? Or, standing passively at attention while she undresses me. I find both to require an equal-but-different (apples and oranges) amount/kind of humble submission. Having to obey her instructions to strip mysef in front of her is humbling/embarrassing. And, having to stand still and allow her to strip me is also humbling/embarrassing.
I usually experience both when I have a punishment appointment with my wife. She will usually tell me to meet her in either our bedroom or my workshop at 7pm (the workshop always means that I should expect more/very severe discipline). I know from experience that I should show up a little bit early and stand in the corner until she arrives. When she arrives, she usually sits down in the spanking chair, and instructs me to come and stand in front of her. She then usually instructs me to strip down to my boxers. I have to stand in front of her, wearing only my boxers, while she lectures me. After she feels that I have been adequately lectured, she will tell me that it is time for me to receive my punishment. Then, she reaches out and lowers my boxers to my ankles, so that I can step out of them. After I am naked, she tells me to kneel on the floor in front of her and look up into her eyes. She asks me if I have anything to say for myself before she tans my hide. I am allowed to say anything, but I know from experience that she will not tolerate stupid excuses. If I offer any excuses, they had better be very good and legitimate excuses. So, usually I just tell her that I understand what I did wrong, I apologize for being naughty, and I tell her that I'm ready to receive the punishment that I deserve. At this point, of course, I am required to put myself over her lap and accept my punishment.
