You ask, is that reaction normal? Define "normal" to me. Having pleasure from being humiliated is not normal to me, but it may be to you. You may be in a very stronghold position in your social or professional life and can't take it, have confidence in your wife to release it by humiliation. Is this "normal"? People just go fishing...
I don't judge you, I'm just stuck on the question "is this normal"?
