Started when I was very young, before school age. I'm not sure why. I must have remembered having it done. I quit between about 8 and 12 when I was at my grandmother s, bored and picked up a toy that resembled a thermometer. I decided to try it and liked it. After that, I'd go in grandmas bathroom, get her thermometer, straddle the tub rim (it was wide), and put it in. I didn't learn to read it until a while later.
I began to do it a lot at home,away,even sometimes at school. I enlisted my best friend who never seemed to mind doing it and would let me do it to him once in a while. As a teen, after being caught by my stepfather, I took it openly, though usually behind a bedroom door. Though more than once he arrived home to find me proudly displaying on the couch. He'd ask if I felt better then tell me to do that in my room.
He knew my friend David often helped but didn't make a big deal of it. Once, when I had David come over, complaining I was ill., He met David coming in and said I was in my room and the thermometer and Vaseline was in the closet. That surprised me.
I left his house at16, came back at 18 for a bit and he came home once to find me nude in bed with a thermometer in and David, also nude, coming down the hall with a filled enema bulb. I tried to tell him that I was constipated and David was only nude because he was changing, but he didn't buy it.
After that, he told me if I needed any medical treatments, I d have to go to a dr. David and I never did anything in front of him again
