A lot of people talk about how much they hated to have their temperature taken rectally as a kid and how they often fought about it.
What about it bothered you?
I never enjoyed them, didn't have a fetish for them, but I found them rather benign. You lie there for a few minutes. It's cold when in first goes in, but only for a few seconds. There was nothing painful, uncomfortable or embarrassing about it. The only thing was when my mom wiped off the lube, she was gentle and didn't get it all off, so I'd have to go to the bathroom and wipe again. But I never really found anything negative about it.
At the same time, it wasn't something I looked foreward to either. If I was sick, my mom (sometimes dad) took my temperature. That was it.
So what did you as kids dislike about it?
