I am circumcised. I am fine with my parents' decision in this regard. But, I just had a son, and we decided not to circumcise him. I did quite a bit of research, and found that there are some definite, small benefits to circumcision, some definite, small risks, and some possible small negatives in terms of sexual sensation. All are so small as to not have factored into our decision. At the end of the day, it's largely a cosmetic procedure. The wife and I see no justification to have cosmetic surgery performed on someone without their consent. So, we didn't do it.
As far as I'm concerned, once he's reached his teenage years, if he wants to have it done for cosmetic reasons, I'll support that decision. After all, it is the norm here in the US. It just needs to be his decision, rather than mine.
