As an adult I was getting a rectal temperature taking which I requested, from a young “trainee” ( the badge she was wearing) as a registered nurse oversaw how the trainee was doing the procedure. The trainee was and I’m guessing 18 or 19. Really good looking, too.
So the nurse lowers my pants and underwear, instructs the young woman, “ You take his temperature!”
The girl grabbed a thermometer, held it up, looked at it, shook it down. Opened a foil packet and plunged the Thermometer into it, pulling it out w/ a good deal of lube( similar to K-Y.) I’d have to think this was not her first temperature taking as I watched her. Seconds later she was spreading my buttocks admonishing me to relax, then inserted the thermometer about 2”.
. After a few seconds she began turning it. I immediately became aroused, explaining it was causing me to get an erection.
She immediately stopped, apologized.
The nurse realizing the situation, told her that rectal temperatures on males and how they’re done sometimes cause erections which were not uncommon.
After a female physician saw me, she ordered an antibiotic.
The nurse did the shot. And my butt cheek (upper part) was sore for a day or two!
As a child, no recollection of my Mother doing that.
