Should we have our son circumsized?

Maybe not. Babies are born complete, finished, and perfectly fine (except for the few unlucky ones with birth defects). Circumcisions are done for religious and cultural reasons, but the procedure does permanently alter the genitals, so parents should think about it and talk about it before doing anything to their perfect little newborn.
Personal choice. In the US circumcision is commonplace, 65-80 %, France 30%,Australia 30%, Great Britain 10% (not covered by national health insurance). There is data suggesting increased life risks of UTI & stds if not.I remember it being the most requested elective surgery among young enlisted men during my navy years. If it is done at all it is easiest and heals quickest in newborns.
