There are quite a few minor benefits to being circumcised (less infection, a small protection in STD's and not having to get it done as an adult because of medical issues), the most apparent being that it's cleaner. And yes yes I know that you can teach the kid to clean it. However, it's very difficult to get most middle school aged boys to wash their hair and wear deodorant muchless clean their foreskin correctly. I've had quite a few friends whose kids have had (minor) issues at some time or another when they were young.

I think it's totally up to the parent and I honestly think it should be up to the father because he's the one with a penis.
