I have always had to wear diapers due to a medical condition and have spent a lot of time in hospitals. When I was a child, it was common for the nurses to change me, but as an adult, I usually do it myself. There have been a few exceptions, for example after surgery or on those few occasions where a night nurse came in to check on me and noticed the bed was wet. When that has happened, I find it embarrassing so I usually pretend to either be asleep or if I was woken, very sleepy and I keep my eyes closed and just do whatever instructions they give me. That did backfire on me once when I was about 23 when the nurse removed my diaper, had me roll over on my stomach so she could wash my bottom, powdered me, and then had me roll over on a fresh diaper and diapered me up. When she turned out the light and left,I noticed she didn't pull the curtain far enough to keep my roommate, who was 50ish, from seeing what was going on and he was laying there smiling at me. I didn't say anything to him and he never mentioned it.
