What is the point of this thread? To insult people who possess a certain physical feature? OP, what was your motivation in wanting to know? Is this a sexual fetish of yours?
Why do you think it is to insult anyone to know why they were left uncircumcised in a highly circumcised culture. I, myself, am uncircumcised and very proud and happy that my cock was left alone. Curious as to why, I asked my parents. The answer was simple. The Doctor did not think it necessary. He had not circumcised his own sons. My parents' friends had not circumcised their sons either. My people, My father, nor grandfathers, nor uncles, nor any cousins had been circumcised, not even the ones who were in or born in the military. NO one had ever had any problems with their foreskin either. Mind you, this is in the 1960s during the height of the circumcision craze. So, I was not circumcised. Most of my friends have been uncircumcised. I have some who are, but most are not.
The circumcision rates have fallen considerably. I understand that less than 30% of baby boys are circumcised today.
There is a bond, a camaraderie, if you will between uncircumcised males in the USA. It doesn't matter if they are gay or straight, black, white, asian, native, or latin etc. it is a brotherhood. Yes, pun intended. It is something held in common. It is probably the opposite for circumcised men in non-circumcising countries.
SO, why were you not circumcised even though you were born in the USA.
