I was told to strip down to my boxer shorts, which I thought was a little strange for a rash on my arms, but at the time I had a pediatrician who had you strip to your under shorts no matter what you went in for, so I just took that in stride... I sure wasn't expecting to be examined completely nude for a rash on my arms.
Similar rash thing here. At my annual checkup at 13, after the exam was over, my mom mentioned to my pediatrician having taken me to another doctor a few months earlier for a rash, but she couldn't remember what the doctor said it was. I said "pityriasis rosea," at which point the pediatrician said, "It looks like someone is able to answer his own medical history now." I smiled proudly, wondering if that meant my mom would not be coming in with me for my check ups anymore. I was an eighth-grader and tired of being treated like a baby. It was too late for that visit, because I'd already been weighed in just tighty whities in the hallway, and the doctor had pulled those down to my knees twice, once on the table for the genital exam, and again while standing for the hernia check, both times in full view of my mom. But what happened next made clear that the babying would continue.
He said, "In that case, let's do a quick skin check to be sure there was no scarring." He told me to get back up on the exam table and lie down on my back again. He then proceeded to pull my undies completely off and hand them to my mom, positioning my legs sort of like a frog, with my knees apart and my feet together. I am sure he had examined me fully naked as an infant or toddler, but this was the first time I could remember lying completely naked on the exam table without the hope of pulling my undies up quickly if someone walked into the room. Not that I had any new development to be shy about -- I was a late bloomer and would not start puberty at all until the next year. I still had a little boy's penis and testicles and no hair whatsoever. But intellectually, I was an eighth grader already scoring high on college entrance exams, so I thought I should be treated more grown-up.
After a couple minutes of them eyeballing every inch of my skin, paying special attention to my abdomen and thighs, where the rash was the worst, he had me turn over, and he checked my back. He then said, "Good, no scars. You can hop off the table." I reached toward my mom for my undies, and she said, "Just wait until we're done." While I stood there completely naked, she then asked if there was anything she needed to keep an eye on before my check up at 14, or if we should come back sooner, and he said everything would be fine, and my 14th birthday exam would be sufficient as usual.
At the time, I was just thinking about what if someone walked in. Only in retrospect did I realize that the extra exposure at that exam, and questions about coming back in sooner or keeping an eye on me, were all about me being a late bloomer, with the rash being just a pretext. Again, if they had simply let me know that all of it was for my late puberty, I would have understood all the extra nudity, even if I didn't like it.
As for the babying of having my mom in future exams to answer all questions for me, being undressed to my undies from the start, including height and weight in the hall, and the doctor pulling down my undies twice during the exam, in full view of my mom, that did not change. It was the same every year, including my 16th birthday. That pediatrician only treated me more like an adult in the final minutes of my final exam, when they both could see that my penis and testicles were at Tanner IV, at which point he finally started talking to me instead of my mom. Unfortunately it was to ask me about my first ejaculation, how many months ago it happened, and whether I was awake or asleep, effectively forcing me to admit to them that I was masturbating. With the exception of those final minutes, that pediatrician babied me my whole life.
