French Canadian here. Catholic background. Large families. And definitely uncut, (most of) the whole lot of us. The one exception being my brother. He was circumcized at birth for medical reasons. The doctor called it: his foreskin was so tight, it would be difficult & painful to pull down, so there was definitely going to be actual hygiene and sexual health issues down the road. But back in '72, they didn't use anesthetics on babes. So they knocked my newborn brother out with a shot of whisky and cut him right then and there. lol.
But my dad has a glorious slab of long, thick, uncut veiny meat, and I'm happy I resemble him in that department (well, aesthetically speaking. He got me beat on size. lol)
