What do you think of a young adult male patient who appears to be wearing diapers by preference? You have no idea about it until he uses his call light to let you know he had an "accident " in his diaper and needs help changing it. He has an erection during this process. Two hours later he does the same, only he has both urinated and and defecated. Another erection...
He has a passive, infantile personality, if you can believe that!
