How I learned what happened. My origin story…
My dad and my sister and I were visiting our elderly neighbors when I was around 8/9, my dad farmed their ranch and we visited frequently. We were on the topic of broken bones and surgeries. My sister broke her finger when she was little, but not me. At one point he said "he's been lucky enough not to not have had any surgeries yet… Well, except for a bit of skin."
The three adults chuckled together. I was literally so confused. I think it was the next day, and I remember the exact spot in the house that I asked him, but I said "hey Dad what did you mean yesterday about losing skin?"
He chuckled a little and paused, and said "when boys are born they have some extra skin on their penis and the doctor cuts it away usually. It's just a little extra skin and getting rid of it helps keep you cleaner." he didn't mention me matching him as an excuse, but it was clear that we did match.
Fast forward a few years I must have just been getting into teen years and I decided to look it up on YouTube one day, and I still remember it. Even the dad was crying.
