I think that one of the first things medical people learn is how to get used to whatever exudates are coming out of patient's bodies.
If they can't get over that, then how could they possibly function in a hospital setting with so many terribly ill people.
And they also have to get over nekkid bodies.
So trying to remain modest is nice, but not at all necessary.
My husband had so many medical problems and hospitalizations. He had no illusions about modesty.
I'll never forget one time when he had been in the hospital for quite a while. They had a skin team of a couple or three nurses at this hospital whose job it was to observe patients for any start of bed sores. They examined the back and the bottom. Well, Joe was standing doing something or other when they came in, and they told him what they were there for, he promptly drop trow and mooned them. They laughed so hard.
