As one Faithful Reader pointed out, too many parents don't teach their sons proper care and hygiene. They expect that they'll magically know what to do.

Just use caution when you visit some of the anti-circumcision sites, because there will be all kinds of bogus information. Being cut when an infant has absolutely nothing to do with the diameter of the urethra.
But, regardless of your situation
take proper care of what you've been given, and it will provide you with all the pleasure it was intended to give.
