I was in hospital as a teenager in the 1970's twice. The first time when I was 14 was quite excruciating because I got rectal temperatures all the time from a procession of nurses all women - and nearly all young. I didn't feel very ill but had a fever and wasn't eating much. Each day they asked if I had a bowel movement and I always said yes though that was usually not true.
Then I was asked to provide a sample - and of course couldn't perform. This went on for several days. Then one day around "temperature time" I was having a bath in a bathroom. Then there were knocks on the door and a tall brunette nurse asked me to come back to bed. But I said I was busy. Every so often the nurse knocked again.
Then to my amazement as I was getting dressed the nurse must have unlocked the door on the outside because she walked in carrying a tray of stuff. She said she had come to get a stool sample, and needed to give me an enema. I did not really know what that was - but I did not like the sound of it. I had to hop up on a trolley and face the wall, lying on my side. Then I was asked to remove my pyjama bottoms. Then just like I was getting my temperature taken, she said I was to pull my knees up.
Next I knew the nurse pulled up my dressing gown baring my bottom, and parting my cheeks with one hand slid something - a nozzle which felt more substantial than a thermometer - up my rear end. She said it wouldn't hurt but would feel a bit funny. There was a long pause and I looked round to see her holding a funnel attached to a tube. She poured liquid slowly into it. The feeling was intense as the water bubbled into me - there was no stopping it!
I was acutely embarrassed and hot and flushed - but worse was to come. I needed the toilet immediately she removed the nozzle. And there was one in the bathroom, but she said I was not to use that. Instead she put a cardboard bedpan on a stool and got me to sit on that. All that water just dropped out of me - with her in attendance! When I had done she got me to get up, covered up the pan, and asked me if I needed any help! No I certainly did not. So she left.
The experiences during that hospital stay were most puzzling. I recall feeling strange (very sexual I later realised) at night. And I got my first noticeable wet dreams in that ward.
