I’ve written about this in other threads, but I’ve had at least two experiences having my anus visually checked by the pediatrician when I was a kid that I can remember. One I can only recall faintly, but the other I remember pretty vividly.
I’ll start with the one I can remember faintly. So, throughout my childhood I had a problem going to the bathroom - specifically pooping, I might as well just come right out and admit it. It’s an issue called encopresis, in which I would hold it in any time I needed to go, which would result in constipation later and soiling when I least expected it. Basically, it meant being constipated most of the time but then having random bouts of diarrhea on top of that. I won’t sugar coat it - it sucked. It was deeply humiliating and it meant many embarrassing visits to the doctor as a kid - and thus gave life to my medical fetish years later. I should also note that this is something I NEVER talk about with anyone as an adult now, but still think back on quite a bit.
So anyway, this first experience - I was three years old. I saw many different pediatricians throughout my childhood, but this was one I saw pretty regularly - an old white guy who is likely either retired or dead now. I don’t remember much about him, but this encopresis issue I had went back to when I started potty training, and my mom brought it up to this doctor. Well, on one of the occasions I saw him, he decided it was necessary to give me a rectal exam. All I remember was that I was just in my underwear, and then naked, and while I didn’t understand what was going on, I still fought back against it, apparently so much so that they had to call in a nurse or two to hold me still while he spread my butt cheeks. I don’t think he actually inserted a finger, but I do vaguely remember my anus being poked at during that check, and my mom trying to explain to me on the car ride home “why the doctor had to stick his finger in my butt.” That could not have been easy for her to watch, and it wasn’t the last time she would either.
So years later (this is the one I remember clearly), my struggle with encopresis had not improved. I was regularly struggling to have bowel movements, and when I did, occasionally at least, I would poop my underwear. On top of that, I was then having pretty bad stomach cramps too from getting “backed up.” So at this point I was right in between 5th and 6th grade and still having this problem, so my parents decided it needed to be fixed once and for all. I was referred to a pediatric gastroenterologist, and my mom made an appointment that summer. To speed this along, this was hands down the weirdest doctor’s appointment I’ve ever had in my life - and as far as my medical fetish goes, was a keystone moment. So my mom and I get to the doctors office, we sign in, wait, nurse brings us back, and the nurse practitioner (female, btw, I’ll get back to this later), does a basic preliminary “check up” on me before the actual doctor comes in, and then hands me a gown to wear. Now, at all my doctor’s appointments before, I had either been fully clothed or in my underwear, but never in a gown, so I felt particularly weird about that. So I changed into the gown, my underwear still on underneath. The doctor comes in (I should note that this guy, at the time, looked almost exactly like Bill Clinton, so I feel strange any time I see pictures or interviews with him in the news), asks some questions about my bowel habits and has me sit up on the exam table. He then has me lay down, pokes and presses around my tummy, particularly lower where my constipation and cramping were, and then pulls on purple exam gloves. I’ve had an association with purple gloves ever since because if I had to guess, he probably had to use darker colored gloves in case any poop got on them, being a gastroenterologist this has got to be a regular thing for him. So anyway, he gets the gloves on, and asks me to roll over on my side, which I did reluctantly with some reassurance from my mom, and I then had to pull my knees in as he pulled my undies down in the back to expose my bare butt. Now here’s the weirdest part - he asked if I would be alright with him putting his finger in, to which I said no, and he agreed not to. He then pulled my butt cheeks apart, peering at my anus for what felt like forever, and saying things like “hm, ah, ew,” - now, it’s likely I projected when I thought I heard him say “ew,” because in that moment I was more embarrassed than I would ever be again in my life, but he was probably just thinking out loud as he was examining me. Everything ended up looking okay with my bottom, and it turns out the reason I was being examined there was because of the constipation issues, and concerns about cracks and tears in the skin from that. After that, I was prescribed a heavy strength laxative, given a routine to follow, and I was cured of that issue from there on out.
So yeah, I think back on those experiences a lot. While they were pretty instrumental in forming my medical fetish, I have to specify that while both experiences were with male doctors, I think back on them wishing they would have been female doctors instead (particularly the nurse practitioner that gave me the preliminary checkup before the gastroenterologist), perhaps then I wouldn’t have felt as weird and embarrassed, as being examined by a female pediatrician is my main medfet fantasy. I did see a couple other female pediatricians during my childhood, and every now and then I think back as hard as I can to recall if they might have also spread my buttcheeks to examine my bottom, but as I was younger, my memory was very faint. Still, the visual anus check is a big part of my medfet fantasies to this day.
