It may be worth looking into the history of circumcision before making a final decision, as there's a lot of misinformation out there, even among doctors. (Please check up on anything I say, as I'm not an expert, I'm not a guy, and I don't have children.)
There's a common belief in the USA that circumcision is a long-held practice that has been maintained by Christians since they split from Judaism, and that it provides a lot of medical benefits. My own research into the topic suggests that this isn't true: there was a wide gap in time between that split and when it suddenly became common again, particularly in America. The reason it gained popularity was the errant belief that having a foreskin made men more likely to masturbate, and there was an era around the turn of the century where this PANICKED people. It's the same reason Kellogg invented his famous bland corn flakes (he believed that spicy foods inflamed carnal desires), and part of the reasoning behind the Boy Scouts (exhausting young boys with physical activity was also supposed to help).

This one is far more anecdotal than the first and I can't find the original source, but the last time I read up on this, I found mention that the US military started to require (or at least highly encourage) circumcision, forcing a lot of men to have it done in their late teens/early 20s. So, when these same men had the opportunity to have it done to their children--to get it over with an age when they wouldn't have to remember the ordeal--they were all to happy to give doctors the go-ahead. And so the cycle continued.
None of this, of course, tells you anything about the medical benefits/drawbacks of the surgery, but it certainly makes the whole proposition looks fishy to me.
And of course, as a general rule of thumb, ALL cosmetic surgery carries risk. A slip of the wrist, and infection, whatever. The risk is small, and if there are real medical benefits, it could be worth it, but it's worth factoring that in.
And as usual, I've talked way too much
Seriously, don't take anything I say at face value; I really don't want to spread misinformation--I'm just spitting back what my own research turned up. Personally, I really applaud you on looking into this instead of just taking the socially-recommended route
