I voted for the male being untied.

I think it is complete domination when he is able to protect himself, but chooses not to. When he willingly allows the woman to hurt him and he accepts his submissive role on his own accord. When he is mentally and physically humbled is true domination.

Or he wants to protect his genitals, but because of the superiority of the woman, he is simply unable to. That scenario is equally hot imho.
