I'm ambivalent about my lost foreskin. I was cut as a newborn as that was the fashion in the time and city where I was born in the '70's. They did a lovely job and it's a nice clean line with plenty of slack (see my pics if you want). I often wonder though what my hood would have looked like. I envision a long fleshy anteater-like overhang, at least an inch or longer, lol.
Anyway, I'm not too fussed really as an adult. I don't feel wounded or cheated by my parents. Where I live now, it's more of a novelty because most people are natural. There are plenty of fetishes for cut cocks and I've never been turned away for having one. Besides, I've known quite a few men who have had to be circumcised in adulthood for various reasons, some even in their 40's and 50's.
Is it good or bad? I would say it's best to keep what nature has intended. But anyone who says it's mutilation is a bit OTT, so if parents want to cut their boys for cultural reasons, it really isn't going to impact them sexually or diminish their lives either. At least I can't tell if mine has been degraded, so I can only speak from my personal experience.
