Oh yes, definitely happened.
- Normally I received suppositories from my parents who had different techniques. My mom only let them slide through sphincter, afterwards I had to lay on my stomach for 3-5 minutes and clenching my bum cheeks together, sometimes she supported me while pressing my cheeks together with one hand. My dad usually pushed the suppositories in me as far as he could. He said that I clenched my cheeks together automatically afterwards so from his side there was no further need for lying on my belly for several minutes.
- My pediatrician showed my parents some tricks / ruses for bringing suppositories in, especially my dad asked for his opinion. For example my dad learned how to push in suppositories with the help of the bigger end of the glass thermometer.
- In hospital tge nurses gave me suppositories. Felt strange because they were foreign. They just let them slide in and pushed up my pants or pyjama trousers. But I got used to it and let them do without any resistance.
- When I was 7yo I met Jonas, a 9yo boy in the same soccer club. We became very close friends, even his and my parents became friends so Jonas and I could spent lots of time together, sleep over and even follow Jonas and his parents to a holiday trip to Denmark. While this trip I got a cold (Jonas too two days later) so Jonas' parents took care of me and even took my temperature rectally and gave me suppositories (same with their son). Felt strange first but it wasn't uncomfortable at all so.
- I had some xxx playmates who gave me suppositories. My first friend came up with the idea giving me a Paracetamol suppository right before to lower pain. When I met another guy during my time in army he did the same. And I met someone when I was 18 I guess who first pushed me in a contraception suppository. I guess he enjoyed the foam, but from my side it felt weird and nasty...
