It might not make any difference on the healthy matter, but it certainly makes a difference aesthetically. The circumcised are much more cute. Not to mention other vantages :) And I think it's better to do it when one is a baby than when one is an adult. I have a friend that had to do it for medical reasons and he went through a huge suffering. I've never heard of a man that was circumcised when he was a baby talking about the trauma he went through.
