My mother was a nurse and strongly believed in enemas as did my pediatrician. I received enemas regularly, at least one a month from the time I was four until i was 12 and 1/2. There was no point is arguing, squirming or crying. The enema was going to be given and retained no matter what. The amount and nozzle size increased as I got older. By the time I was 8, I could hold 2 quarts for five minutes with a douche nozzle used for administering.
My sister was two years older and started attending my enema session against my will, when I was age nine. My enemas were always given with me on my back and my legs pulled back. So when i started getting erections at age ten, my mom and my sister had a full view.
I got used to my sister being there, I never got to see her get douched (done monthly with a lot of screaming after every period) or her multiple enema sessions, again accompanied by a lot of screaming.
When I was 12 and 1/2, my pediatrician suggested to my mother after my first full rectal exam, that it was a good idea for teenaged boys to be cleaned out with an enema series once a week. My mom thought this was a great idea.
She came home from her nursing job at the hospital with a special nozzle to help me retain my enemas. I later came to know it as a balloon nozzle. While my dad was at work on Sunday morning my mom and my sister would give me a three enema series. All enemas were two quarts, one with Castile soap and two large volume rinses. Because the nozzle was so large my mom took to lubing my inner sphincter with large amounts of Vaseline.
Many times, mom would invite freshman nursing students to the house to learn how to properly administer an enema to a adolescent. I was always instructed to be very clean for the student nurses. She had them prepare the enemas, prepare the nozzles and prepare my anus and rectum for insertion. These sessions sometimes went up to five enemas over a five hour period.
When I would become erect and I always would, she would tell the nurse that my anus and prostate were stimulated by the touching and the nudity and the enema itself. She told them it was perfectly natural.
I had the last of these sessions when I was seventeen.
