Can you remember your first anal insertion.

Rectal Thermometer. It's all I had for most of my early exams, into my early teens. I had a digital exam this year, and, well, that was interesting...

As many of us raised in the 70s, I was no stranger to rectal temp readings. My earliest recollection is getting one at age 4 from the nurse at the doctor's.

I think a was about 4-5 years when nurse gave me an enema using enema bulb.
