My husband is circumcised and still feels a bit of residual anger towards his parents for making him have a circumcision for no reason other than his father is circumcised. When we had our boys, he demanded that they be not circumcised. That way, when they are old enough to make the decision for themselves, they can. It's one of those things that you can't undo once it's done.
I would say just do your research so you understand the arguments for and against circumcision. Most of the reasons that have been touted in favor of circumcision were debunked long ago, but continue because they are traditional, but not medical necessary. And remember, this is cosmetic surgery (cosmetic meaning not medically necessary and can actually negatively affect sexual pleasure down the road), and like any surgery, something unexpected can (and occasionally does) go wrong. I'm not trying to scare you, just reminding you that this is, in fact, surgery.
In short, do your research and do what you will, but understand the pros and cons before you make that decision. Once done, it can't be undone. Personally, I would say if he has gone this long without one, why do anything at all?
