This isn't a millennia ago. This is now.I can't believe this is really a thread.... Circumcision is credited with saving lives millennia ago, that is why societies that developed around sandy areas generally developed this ritual. The ritual needs a reason so they accredit it to some diety, hence it becomes part of a religion. I'm not Jewish but I am circumcised. Every man thinks different of their penis, and every women thinks different of how a penis looks. If you think about it, genitalia looks pretty damn weird, no matter what you do to it.
I'll have my children circumcised because then its over and done with, they wont' remember the "trauma", and they won't have to go through it later in life when they will. Plus most women I've been with have said they have preferred cut to uncut, many said the uncut would pull or pinch.
