The masturbation thing is not all that uncommon.
When on the transplant service, we had a patient who masturbated every day during rounds. As in both resident rounds and attending rounds. When a new "prim and proper" attending with no sense of humor came on service, there was this awkward interaction of us explaining to him that the patient masturbated all the time. He got frustrated that we didn't just tell him to "stop it". He didn't listen to us when we said it wouldn't have changed anything. The attending marched in there and predictably, the patient is going at it, and of course, doesn't stop despite my attending telling him multiple times to stop, trying to move his hands, etc.
It was awkward yet hilarious. The attending got pissed and stormed out of the room. Why he bothered to tell an encephalopathic ESLD patient to stop masturbating, I'll never know. The other transplant attendings found this whole story absolutely hysterical.
