The first time I got an erection during a physical exam was when I was the pediatrician was checking my foreskin. I’ve read stories here of the doctor painfully yanking back boys’ foreskins, and thankfully my doctor was a lot gentler with me, even though my skin was pretty tight when I was younger. Anyway, the doctor was trying to pull my foreskin back, but it was so tight that he couldn’t quite get it fully retracted. I felt myself starting to get hard, which only made things tighter. After lots of gentle tugging back and forth over my head, I finally sprung a full erection, and my foreskin finally slid all the way back. Then he told me that I should regularly retract my foreskin like this in this and explained how to clean the head of my penis, all while still holding my hard cock in his hand, with my bare head visible to everyone else in the exam room. After checking my testicles, he said something like “let’s fix your penis now”, and pulled my foreskin partly back over my head…but because I was still hard, my glans was still partially exposed. I didn’t apologize for getting an erection, and the doctor didn’t comment on it, but I was definitely embarrassed. Plus I was fidgety for the whole car ride home, as I felt my sensitive head brush against my pants.
It was a lot more embarrassing when I had to see a urologist as an adult, and got an erection when he gave me a prostate exam. By this point in my life I was well aware of my medical fetish. So my dread of going to the urologist was two-fold…1: I was terrified of actual doctors/medical exams, and 2: despite that, I was afraid that I would get an erection and the doctor would think that I’m some kind of weird pervert. I mean, I AM a weird pervert, but that's none of their business, and in this context I was not turned on by the idea of getting a prostate exam at all, just terrified. To make things worse, the first thing I noticed when I walked into the exam room was the tube of surgilube and a box of XL gloves (ugh, why wouldn’t they hide those!). Despite my genuine fear during the exam, I was half-hard by the time the doctor finished with the external genital exam and told me to bend over the table to get my prostate check. He plunged a finger inside, and I remember thinking that this felt nothing like the prostate exams I had given myself, or the times my ex boyfriend had fingered me. This was rough, sudden, and hard, and as soon as his finger was inside he started pressing deeply on my prostate. By then, I was fully hard. I wasn’t wearing a gown, so the doctor saw everything. I wish I hadn’t acknowledge it, but I was so embarrassed that I said “I swear I’m not enjoying this” (which was partially true). The doctor replied with something along the lines of “I know…that’s a natural reaction”. Then it was over, and he took his gloves off and started explaining to me how everything felt normal, and that my problems with urination therefore weren’t because of my prostate. He even drew a diagram on the paper of the exam table of the prostate and urethra, explaining how this anatomy worked. Meanwhile I’m standing there still erect, still naked (it felt awkward to get dressed while he was still talking to me). I just remember thinking what a crazy situation this was: here I with my pants off, fully erect, having a conversation with someone who had just violated my ass. Before leaving the room so I could get dressed, he told me I would have to get a cystoscopy, which is a story for another time.
