The difference is that the patients were unconscious and couldn’t give consent. Did she touch him to get a better picture? Stimulate him? Well endowed or not, no man should be wondering what filthy hands touched his private parts when unconscious.
In no way, at any part of this was there anything right or moral and she knew it. You don’t take advantage of sick people for laughs.
She should be publicly caned.
You brought women into it as a comparison. I am addressing that aspect of it. Remember that men and women are different.
Guys don’t really worry if a cute nurse gropes them while they are asleep. (Most guys would actually volunteer to be truthful)
Was what she did wrong? Absolutely.
Would the guy be upset? Probably not (if he wasn’t tiny)
Men and woman are different after all.
