There were 2 instances, both around the same time
.I was probably about 11or 12 at the time. For some reason, my Mom took me to the doctor. (It may have been a normal physical for before the school year.) My normal pediatrician was out of town, and another doctor was covering for him. Actually there were 2, a husband and wife. I never met either of them before, but my mother knew them. I understand that the husband was a rather surly fellow who was rather gruff with his patients. Fortunately (or unfortunately, if you are a pubescent shy boy) I got the wife
Anyhow, the exam started as normal, strip to my shorts, height, weight, temp (oral by then) etc. So, I'm sitting on the table in my skivvies on the table waiting for the doctor, my mother sitting in a chair across the room. In comes this woman, and she introduces herself to me as the doctor, and told me she would examining me. I had never had a female doctor before, and, as I indicated, I was a rather shy kid, so that was surprise #1. My mom had a bit of chit chat with her, then she turns to me.
She was friendly and quite gentle, but efficient. She did all the regular stuff, HEENT, listened to heart, lungs, and abdomen. She palpated my abdomen, including just under the waistband of my underwear. (Nothing unusual there) She then checked my range of motion, gait, scoliosis check, etc, (Again, nothing unusual) then had me stand in front of her.
At this point, my normal doctor would have simply looked into my briefs to see that everything was OK. I was a bit nervous having a woman do that, but then came the biggest surprise of the visit.
She pulled my underwear down my upper thighs. (Now getting really embarrassed) She skinned back my foreskin, My doctor had done the same, but remember, I was a shy lad who never was examined by a woman at a time when I was just becoming aware of girls, and had had Sex ed the previous school year. (Although, I don't remember getting regular erections for at that time.) After this humiliation, she did something my doctor never, that I remember, did. She grabbed my scrotum and gave my balls a gentle squeeze. (Totally unexpected) I felt a tingle in my balls, but, fortunately, did not become erect. She then pulled my underwear back up and had me sit on the table. She told my mother that everything was good, told me to get dressed and left the exam room.
I dressed, then we went out got some paperwork and left. Of course, I told my best friend what happened, and we had some adolescent talk about that. I often thought about that often as I sailed into puberty.
The second instance was in the summer. I was about 13 at the time. It was a August, so I slept on the floor in the den and not in my bed upstairs. (My room was terribly hot in the summer) My Dad was out mowing the lawn, so it was probably about 8:30 or 9:00 in the morning. I woke up, and I was covered in hives, and my eyes were swollen. Mom called the doctor, (My regular doc this time) who sent us to an allergist. (We did not go to my doc at all, but that was not unusual at the time.) We knew it was not chicken pox because I had had them a few years before, and my MMR was up to date, (Also, i was the 5th of 6 children, so Mom had seen and dealt with most of the normal childhood diseases, as well as poison oak, poison ivy, and poison sumac.) so, off we went.
We got there and, Mom filled out the paperwork. After telling him the problem,( Which had subsided some by the time we got there) and he had me take off my shirt. (The first time I was not told to strip to my shorts for an exam, which was OK with me because my mother was in the room with me.) At this point, being naked in front of my mom would have been...awkward. (This visit also marked the last time that Mom ever went into the exam room with me.) He inspected the hives on my chest, arms, and back, then my legs,(It was summer so I was in shorts.) and feet, then he had me lie on the table and he started doing the normal exam stuff. After a bit, he told me to remove my shorts. I was surprised, and so was Mom. (We expected him to just look at the rash and be able to identify it.) Mom and I both protested strenuously, and he said to my mom "Is he wearing clean underwear?" Mom replied "He better be!" so, off came the shorts and underwear. He checked under my penis, scrotum and my whole groin and upper thigh area.(This was about the time that my pubic hair was starting to sprout.) Then he had me turn over and checked my buttock, separating the butt cheeks. (It's a good thing my face was already red from the rash to hid my blush)
After doing a thorough exam and I was dressed, (Or possibly before the exam, it was long ago) he did a scratch test.
The final diagnosis was an allergy to grass and ragweed. He gave me some medication and told Mom to have me follow-up with my regular doctor.
As I said, I think when Mom saw that I had, indeed, reached puberty (Pubic hair and larger genitals plainly visible) this was the last time she came into the exam room with me.
