I am now in my mid 40's now and will confidently say that only one time was it memorable having my temperature taken rectally over 30 years ago.
I only share this experience now due to the anonymity of the Internet.
Okay, so where to begin... being born in the late 70's it would not surprise anyone here that for very young children who would not hold a thermometer in their month, temperatures were taken in their butt. That is simply how it was done... oral or rectal there really was not any other way to do it until probably about the mid 90's for ear thermometers as far as I know. That said, I have barely any memory at all having my temperature taken at 2 or 3 years old, and my parents stopped that method pretty early, but I am not here to write about an early childhood experience because none of those experiences are memorable.
You see my temperature was never taken rectally again except once... when I was 15.
I know what you are thinking... "when you were 15, really?"
Well, there is a backstory. I grew up in Washington state where it was quite cold in the winter at times. It was 1992, and I was 15, and this event occurred before I got a driving permit. Back in the early 90's friends and I used to enjoy riding our BMX style bicycles and we enjoyed all outdoor activities; it is what we did for fun. We could come and go from the houses when we wanted with very little parental oversight compared to today's standards. Anyway, it was a particularly cold day and for some reason we rode our bicycles in T-shirts (yeah we had jackets), but we never put them on this day for whatever reason I am not sure. Long story short, we rode through creeks some from giant hills, it started raining, but we were having way too much fun to care. I remember being entirely wet by rain and feeling cold to the bone then very cold to the point it hurt to be cold and beyond shivering. You would think any intelligent children would go dry off and change, get a jacket, but not us that day. I was probably also too afraid my parents would make me quit riding my bicycle with friends if I went inside to change. Anyway, to get to the point we sort of felt numb and saw that as an improvement because we were still having fun and it didn't hurt to be cold anymore.
Then we went inside to our separate homes, and I remember my mother freaking out. I remember I am having a hot shower and shivering and freezing in the hot shower. She took my temperature orally and it was a bit low and some calls were made. At some point, I am told that we are going to the hospital so they can check me out. I am of course entirely alert and feel fine but shivering like crazy and uncontrollably now probably looking like I am having mini seizures in the car, but I am just shaking to the core.
When I get to the ER, I am admitted immediately and brought back. At some point I am separated from my parents and questioned... I tell the hospital staff I was riding my bicycle with friends, and that I have a jacket that it is with me... but I did not wear it, but my parents even had me bring it to the ER (parents probably embarrassed). I remember then being asked to change into a hospital gown and then this young nurse installed an IV which freaked me out, but she never actually hooked it up to a bag. She just told me everyone gets one. She takes my temperature orally and walks out. Shortly later she returns within a few minutes that she said next caused my heart to sink to the pit of my stomach and skip more than a few beats and start pounding like crazy in my chest. She said she needs me to remove my pants but keep my underwear on and get on all 4's on an exam table in the room because the she needs to take my temperature in my butt. Keep in mind, I am 15 and she is in near early to maybe mid 20's and gorgeous, and I am petrified having never been seen naked by someone else let alone a young beautiful woman who is going to take my temperature rectally. It was almost too much for me to process, so I just went into auto pilot and did what was asked. She tells me when people are hypothermic that it common even in adults for the doctor to order the nurse to take their temperatures rectally because it is the only accurate way to get a true core temperature.
I say nothing still just on autopilot doing what I am told, my heart pounding almost out of my chest... my knees quaking as I get up on the table. She then has me drop my underwear to my knees while on all 4's and I remember looking back as she put some lubricant jelly of some sort on the thermometer that looked long , but she assured me it will not hurt but that it is normal to feel very strange when she puts it in my butt that it is perfectly normal. She was just very matter of fact about everything she said. Anyway she just barely inserted the tip and that was really it but a couple of seconds later it sort of fell over and fell out on the tissue paper on the exam table. Saying nothing she just picked it up and put the tip back in how it was and the same thing happened again. After falling out twice, she said for me to just relax and be calm and try not push it out to which I said I wouldn't. She put it back in and I felt it slide in a bit further maybe even a couple inches. I sighed and maybe gasped. This is the third time this anal probe has been in my butt (albeit not for very many seconds), and now I say, "I need to poo." She removed it immediately and said to go ahead. I went to toilet but did not actually have to go poo. When I returned, she said, "you already went?" I responded, "I thought I had to go but I didn't." Then she told me that the thermometer may make it feel like I need to go poo when I don't, but let's just get this over with and to remember not push it out because each time it comes out she has to start over and it needs to be timed that this will take several minutes (she showed me her stopwatch). Okay, so she slide it back in my butt for what is now the fourth time and I felt it go in somewhat deep like last time this time maybe a bit further up than last time I said I needed to poo. She certainly always inserted it gentle and slow. I absolutely sighed and started breathing somewhat heavy. It just happened automatically.
Now keep in mind at this point in my life over 30 years ago I am 15 and that a couple of years before this in the privacy of the bathroom at home I learned about masturbation when I had my first orgasm and since then pretty much began that habit, so I was aware of my penis, and not only that, at that age sometimes it was more than a once daily event. This is simply how my penis behaved back then. I could so easily get an erection back in those days for any or no reason at all... it was crazy! Not only that being young and in excellent cardiovascular health, I remember these erections being so hard I could support the weight of a wet bath towel! I know you can sort of figure out where this story is going next.
Yes, it was embarrassing but I am on an exam table with a thermometer up my butt pretty deep, and I am clearly squirming a bit and breathing a bit heavy with a young 20's nurse watching... then my penis suddenly with mind of its own went from a little peanut (severe shrinkage from being cold) to a raging, fully-erect hard-on. It just happened and was even more embarrassing! At that age I was full height 6' 3" (1.9 M) tall, and while I was never a freak of science, my penis was already proportional to my height. Yes, I had a man's penis NOT a boy's penis is what I am saying. Even as an adult it never got beyond 7.5" (19 cm) length and never more than 6" (15.3 cm) circumference (girth). Back then at 15, it was already about 90% of it's fully-grown adult size. Given that the real average adult male penis in the USA is only about 5.25"(13.3 cm) in length and 4.6" (11.7 cm) girth, even back then I was legitimately more than an 1" (2.5 cm) bigger in both length and girth than an average adult penis, and she definitely saw that it was a "grower." Not only that at the time, I was physically fit and skinny, which I am sure only made it look bigger, oh and I did not have a lot of pubic hair, so looking back, I am certain she was looking at what in her mind had to have been an absolute monster erection for anyone let alone a 15 year old. The nurse did NOT say anything and was totally professional, but I do remember looking back up at her and seeing this HUGE ear-to-ear smile/grin, and I could tell that she most definitely was looking at it. I know it is human nature. I will say she was a true professional and did not touch the thermometer anytime after she inserted it, and she never touched my penis.
At any rate as I am still looking back at her, I feel the thermometer completely slide out. She re-inserts for what is now the fifth time and what felt so very deep, and she tells me she is restarting the timer. I hear some beeps. "I am NOT trying to push it out," I tell her, and I hear her say to "just keep relaxing and stop pushing it" and to "think of something else," but I cannot think of anything else! I then say, "It feels really deep." She says, "It's right where it needs to stay." Right then I feel it start moving again and say, "it's moving" but this time as she grabbed it and stopped it from coming out. Instead of just holding it in though she just s-l-o-w-l-y starts pushing it back down to depth and it felt like it was going in so far! As she was sliding it in though, I start to have this very strange and new pulsing or throbbing sensation start building in my butt which is now involuntarily gripping the thermometer tight and clenching down on it like my insides are chewing on something. She pauses mid insertion and says, "you're okay but this will go easier for you if you just relax?" and just as she said that she resumed pushing it in the rest of the as I was still clenching down hard on it. At this point I felt what I can only describe as some pleasurable pulsing and involuntary throbbing going on with my insides especially while she was pushing on it. I am not sure why she isn't just holding the thermometer, and I sort of look back at her and see she is clearly just looking at the timer. I feel like the thermometer is now finally staying put on its own but that my butthole is sort of clenching and releasing clenching and releasing and this sensation is now is just sort of going on continuously on its own. While that was happening she says, "stop clenching " and follows with "you just need to relax because when you clench it slowly starts moving and we are almost done." I hear her sigh and feel her slide it back down just a little bit while these gentle rhythmic clenching cycles are going on and take her hands back off all while still looking at a timer. At this point, a couple of droplets of pre-cum came out of my penis and dripped out on the tissue paper on the exam paper. She did not say anything or giggle or anything, but I heard her sort of exhale sharply. She saw it.
The timer goes beeps and she takes the thermometer out and hands me a tissue telling me to wipe my penis. I did NOT have any orgasm, and she tells me to pull up my underwear and put my pants back on then to get in the room bed and wait until she talks to the doctor. She comes back a bit later and asks me if I want anything to eat to which I say "a popsicle," and she says, "nothing cold because I am going to have to take your temperature orally and if it is not higher than it was in your butt, we will need to take it in your butt again." I say nothing, but secretly I almost want it again because as embarrassed as it was I was very much aroused and this was by far the most erotic experience I ever had. Anyway, I get a snack from some other nurse. Then the butt nurse comes back in with the biggest, brightest smile, and says, "how is my big guy doing?" Then she says, "I need to take your temperature, so open your mouth."
At some point, I am discharged and sent home the same day. I never said anything about it to my mom or anybody ever and it has been over 30 years. I get home and my Mom feeds me. I then say, I need to take a shower to which she said, "didn't you already shower?" Me: Yes, I forgot. Of course Mom was like, "you have had a long day. I bet you are tired." Me: yes.
I remember hopping in nice, warm bed in a warm room, with a fully belly, and with that new memory. Of course, that evening I had an absolutely raging erection as I thought about what had happened, and I blew my load in probably 20 seconds.
I have never had my temperature taken rectally since, but boy will I never forget that day in 1992.
