When I was 5-9 I had my bed in a corner of our kitchen and I don´t remember anyone seeing me having a rectal temp except my parents. At that time I didn´t bother so much about it neither.
From 9-14 I shared bedroom with my sister and we could always see each other having the temp taken. At this age it really became more and more embarrassing having my temp taken by my parents as I matured and my sexual feelings became stronger and stronger. But except my parents only a doctor and a nurse saw me having a rectal temp a couple of times.
But it happened that my temp was taken sometimes while we had guests at home. At those occasions I was afraid they might suddenly enter my room.
I remember a Christmas we were a lot of people at home both younger and older. I was 14 at the time and I have had a cold but it was more or less over. Suddenly my parents came into the room and annonced so that everyone heard it: "It´s time to take your temperature. Take off your trousers and go and lay down on your bed and have a rest while we prepare the thermometer for you".
I was chocked. terrified, embarrassed! I was 14 and now everyone knew that I was going to have my temp taken in my bottom like a little child. But putting up a scene would only make the hole thing even worse I knew since earlier experiences.
So I obeyed them went to my room took off my trousers and layed down in my bed as so many times before.
Laying there I could as usual hear the preparation of the detasted (and secretly beloved) instrument from the bathroom next door. I also heard the voices of some people who was obviously following the preparation process of the thermometer and I understood that my temptaking was now the big issue out in the other room among my relatives.
Suddenly they stood in the door opening with the prepared fever thermometer in their raised hand. Together with them was the cousin of my daddy. She was a very beautiful young lady only a few years older then me. She was just about to have her first baby and now she was invited to learn how to take a rectal temperature.
I was going to be demonstrated upon. I was 14 and I was all red in my face of shame to have to show my most private parts not only to my parents but also to her.
I knew protests never helped - it always made it worse in one way or the other.
Soon my underwear were down my buttom separated and the thermometer were inserted inside me. They discussed different positions. How it was more easy when I was a small child to have me on my back and lift my legs up while inserting the temp. Or having me over their lap. I was mortified and scared they were going to demonstrate also these positions on me.
After the usual three minutes the temp was removed. They checked the reading but explained that they always use to reinsert it for another two minutes to be on the safe side.
Now the thermometer was handed over to the beautiful young lady. She was invited to practise on me! My bed were standing out from the wall so they were sitting on both sides around me. I felt one hand on my back to calm me down but also ready to hold if necessary.
Two other hands opened me up and presented my most private part so the insertion could start.
Now somone knocked the door and without waiting for an answer to enter the room suddenly my aunt and her 11 year old son - my cousin - were entering the room.
She explained that her son complained about his rectal temptakings and liked to switch to oral. But she found it to be a bit to early. She wanted to show him that even bigger boys like me still got their temperatures taken rectally.
Now five people were standing or sitting in and around my bed while the "show" went on...
Again my bottom was separated and again the insertion started now with a lot of hungry eyes watching it. The young lady was not so skilled as my parents. It hurted a bit now and then and she had to remove and reinsert it several times before she got it in place deep inside me.
They were discussing temptakings around my bed and they were all strong belivers of the advantages of rectal temptakings.
"I don´t want to have my temp taken like that. I´m not a baby anymore", I heard my 11-year old cousin complaining. He was wildly complaining and also teasing me as I was laying in front of him with a thermometer deep inside my bottom though I was much older then him.
"Don´t you have another thermometer? I think this young lady needs to practice also on another little boy", my aunt asked my parents. And she didn´t have to ask twice.
Within a couple of minutes they were back with next thermometer. My cousin protested but in wein. He was undressed and layed down in my sister´s bed next to mine.
They all had to concentrate on him to get the thermometer up his butt which was not so easy. Meanwhile they forgot about me but soon we were laying there beside each other while the temperatures were taken on both of us at the same time.
I had it inserted a long time already but they let it stay in just to show my cousin such a "good and brave boy" I was.
Finally it was removed and so was my cousin´s. I was embarrassed afterwards to have been demonstrated on but he was even more. And "thanks to me" I knew that he got his temp taken rectally many more years...
