Hmm. Where I come from, boys get circumcised pre-puberty as a rite of passage. I don't think it has anything to do with religion. It's considered a thing of great shame if a boy reaches a certain age and hasn't been circumcised yet. And of course, even if he doesn't want the other kids to know he hasn't been cut, they'll find out anyway. His mother/grandmother/aunt will probably tell the other kids' mothers/grandmothers/aunts. I have no idea why. That's just the way it is. For this reason, along with a lot of others, I am glad I'm a girl. :P
