I know my parents made the best decision with the information available to the at the time of my birth. I've no animosity about being circumcised, wish I hadn't been based on "modern shared knowledge", but I am & the Dr. did a good job of it & the result has always been rather pleasant aesthetically.
But, I did out grow the tight circumcision the Dr. did. As a young man (of 18) my erections would be painfully tight, the glans turning shiny it was pulled so tight. I didn't realize for decades that erections weren't intended to be so unpleasant. I've done some foreskin restoration & my goodness erections are a world of pleasure better! Ah & as
@ColonelLingus says, my balls became less tight as I grew more shaft skin. They used to make me nauseous in the cold they'd get so tight, not so anymore.
I'd say circumcisions should be done after maturity, once a cock has grown into what it will be, with owners informed consent. If that doesn't become the normal, then at least have a conversation to determine a best guestimate of potential adult sizing. IMO
