Prior to my teens, I don't recall eye contact, probably because my mom would stay seated in the chair at the end of the exam table.
But at 13, at the end of my exam, the doctor decided to do a skin check for scarring, ostensibly because I'd had pityriasis rosea a few months earlier, for which my mom had taken me to another doctor when my pediatrician was unavailable. For this, my mom stood and watched, as the doctor had me lying on my back on the table, while he removed my underpants completely for the first time since I was a baby. In retrospect, I realized that this was more about my having not yet started puberty at 13. But even then I don't recall registering their concern at all.
From that year on, instead of staying seated, when the doctor would say it's time to check the plumbing, my mom would stand up to watch as the doctor pulled my undies down to mid thigh for what felt like an extended genital exam. At 14 was the first time he said the words "late bloomer," and not knowing what that meant, I definitely noticed the concern on my mom's face for the remainder of the exam. But she never made eye contact with me. She just watched the doctor as he palpated my testicles and penis. I also heard it in her voice when the doctor said I had just started puberty, and she asked how he could tell, for which he brought out the orchidometer and showed her my testicles matched the bead with the 5 printed on it, which meant puberty had started.
At my exam at 15, I was searching both their faces for an indication of concern even before the doctor pulled down my undies. I guess my testicles had grown quite a bit, such that the orchidometer did not come out again. That year, my mom's questions as she watched my genital exam were about how dark my skin had gotten and when my penis (she said "peepee" but the doctor was professional and used the word "penis") would start growing. He reassured her that it had started getting longer but was hidden by the fat pad from my putting on so much weight that year. Again, she made no eye contact with me.
At my final exam with that pediatrician at 16, as soon as the doctor asked me to lie back on the table, I was watching his face to see if he still was concerned. When he said it was time to check the plumbing, and my mom stood up to watch, I definitely was looking to see her reaction when the doctor showed her my penis and testicles for the first time in a year. Finally, she seemed relieved, as I had done a lot of growing in that last year, including slimming back down. But as usual, she was not making eye contact with me, instead paying attention to my genital exam. When the doctor asked me when I had started ejaculating, and I said a few months earlier, they both looked satisfied, and he said I had caught up. For the first time, the nerves melted away, and I wasn't worried. The doctor then proceeded with palpating my testicles, and for the first time, without the severe anxiety of being a late bloomer, my penis started to stiffen. By the time he finished palpating my penis, I was fully erect. The doctor quickly pulled my undies back up over my erection, and only then did my mom make eye contact with me and smile reassuringly.
