I grew up in 1980's Australia and as far as I knew, I was the only uncircumcised kid in my school (junior and senior schools).
i was extremely self conscious about it. Starting in year 3 and going until year 6 (so from age 7 to 11 or so), I was bullied mercilessly. Groups of kids would grab me after school, pin me against a wall (out of sight of teachers and parents of course) and pull my pants down, exposing my uncut dick for all the world to see. It was horrible, but even more so when there were girls in the group of onlookers. In hindsight there were a few Greek kids at the school as well, and they probably would have been uncircumcised, but they kept to themselves. I looked like all the other kids, so I was marked as the freak. My brother was also uncircumcised, but he was 7 years younger and more kids were being left uncut in his age group, although I do know my mother would often catch him in the bath with his foreskin retracted. I don't know what his experiences were though, and we're very different people. Knowing my brother, he would have hit anyone who tried to tease him. I was always more placid than him.
I never told my parents. Too embarassed.
We moved state before I started high school. I avoided being naked in front of any of my peers. Occasionally talk would turn to circumcision - first when kids started learning what it was (probably age 13 or 14 at my school) and then when they became sexually active. Being uncircumcised was always either the unfavourable state, or the unknown state, or both.
"I saw a picture of an uncircumcised cock. Ewwww - it looked so gross.."
"Have you ever seen a dick with skin on it? Oh fuck no! Why would I want to?"
Conversations like that between girls would make me feel very self conscious. I heard them often.
I became sexually active after high school when I was in college. My first girlfriend didn't like my foreskin and told me so. She'd pull the skin back and say "that's better".
Other partners also expressed a mild preference for cut guys or told me they didn't care. For all but one of them, I was the first uncircumcised guy they'd been with. The exception was a Finnish girl I met while I was travelling in Europe.
Some years after uni I had a heavy night of tequila drinking and tried to get into my jeans the next morning without any underwear. I wound up catching my foreskin in the zipper and the amount of blood I lost freaked me out. The doctor at emergency said they cold try and stitch it back up but it could become tighter, or give me a circumcision. I opted for the circumcision and have been very happy about it ever since (although I suspect my self consciousness about my penis was probably a deciding factor there).
As luck would have it, I wound up marrying a European girl, although she'd had a circumcised partner before me. She has no preference at all apart from thinking it looks a little neater without the foreskin.
