Genital exams were included in every childhood physical exam, but I didn't think much of them until starting puberty. It was probably around age 12, and continued this same way until my last exam at the pediatrician at age 16.
Both my parents would take me and my younger sister to exams the same day. Once I started puberty, my mom and sister would be together and my dad would be in the room with me. I was very self conscious about being seen and touched.
They were in the summer, and I would be wearing shorts and a tee. I was stripped to just shorts and underwear (briefs) from the very start. The exam would progress, and I would be told to lie back on the table. The doctor (male, late 40s), would palpate and auscultate my upper abdomen. For every single exam since puberty, this caused an immediate erection to develop in my pants knowing what was about to happen.
Moving lower on my abdomen, he would undo my belt, button, zipper himself and open my shorts wide. He would then lift the waistband of my briefs with one hand, while the other hand moved to palpate my lower abdomen. As soon as he lifted the waistband, he was met with my fully erect penis pointing straight towards him. He would palpate my bladder underneath it, brushing it slightly with his knuckles.
“”Okay, I need to have a look all the way down here." With that, his attention shifted to my penis. He would spread open my urethral meatus, and then shift my boner from side to side, up and down to check out all sides of it. I remember raising my head, looking down and seeing my hard dick in his hands. He put a hand on my chest, pushing me back down, and said, “Just relax.”
He would then insert his hand all the way into my briefs with his palm resting on my shaft as he rolled my balls between his fingers. After a few seconds of this, he would begin removing his hands, and fasten my pants.
This was all with my dad sitting on my right side with me up on the table at his eye level. No hernia exam, and it was always done lying down. He would tell my dad that “everything looks good in the underwear area.”
