When I was a child and early teen, my father always took my temp ,rectally and with a traditional glass thermometer lubricated wit h wazeline. He used good time, spread my buttocks wide apart and my anus open before inserting.
My mother stood in the background and watched.
I usually lay on my left side with legs flexed up, but sometimes at my back with flexed and spread legs.
Thereafter he wept my anal area free from wazeline with toilet paper.
He often felt at my lower stomach parts, at my scrotum and my hip joints thereafter when I again lay straight at my back.
Sometimes my father also inserted a finger into my rectum to probe my anus and my prostate.
The whole felt more like a pelvic exam than like just temperature taking.
What told so far is what happened when I was awake. But he also took my temperature early in the night or very early in the morning when I was heavily sleeping. I think i got some medicine to sleep hard.
I am sure my urine was emptied with catheter before I woke up in the periods when I was most sick in my preteen and early teen years. They injected some medicine into my urethra, which I actually remembered. I do not remember that they inserted the catheter, explicitly. But when I woke up my bladder was totally empty and I had no need to pee before late in the day. I wondered actually at the time why I did not have to pee. But I had some slight pain in my urethra and my genitals were totally flaccid as if they were numbed out which also made me wonder. I think the one doing it was a nurse living in the apartment building that everybody could call to take care or sick people. I think she earned taxfree money from it.
My father was equally eager to look into my throat and check my breath by listening with an ear at my breast.
I know actually why my father did these things. He was afraid I could have rheumatic fever, bladder infection or appendicitis, conditions that are surprisingly common in Norwegian kids.
