I was circumcised shortly after birth. Back in the 1950's this was a routine operation for all newborn males. We were required to change and shower starting in Grade 7, which corresponds to 11 to 12 years old. Back then, this was strictly a hygiene issue, and no one got exempted out. As such, unlike today's young men, I had the opportunity, starting at age 11 and throughout my school years, to see my peers naked. What this meant was that a) you realized that not all guys are created equal and b) the differences are utterly insignificant.
My doctor left behind a lot of foreskin, and since my early teenage years included out of control hormones, and almost non-stop jacking off, I guess I stretched my foreskin, because today it covers about 90 percent of my cockhead.
I never really thought much about it until the middle highschool years, when a friend surprised me by commenting on it, as we were drying off after our phys-ed shower. He said it was nice to see another uncut guy, as he was occasionally teased about his "weird-looking" cock by one of the more ignorant guys in his class.
I pulled back my foreskin to show him my circumcision scar, he was quite surprised. But this conversation led to many mutual jackoff sessions after school, when we did our homework together, so I was a very happy, extremely horny chronic masturbator.
