There was a long post a looong time ago explaining exactly why one should NOT inflict such a thing upon his son.
First of all: "It helps keep it clean!" Bullshit... soap helps keep it clean. Hell, what gets dirtier every day? Your face (exposed all day long) or your feet (socks and shoes covering them all day long).
Secondly: I'm told that circumcision results in less sensitivity for the man when "the time" comes.
Thirdly: "It looks better!" blah blah blah... pull back the skin and I bet not even the peepee-doctor could tell the difference.
Besides, if he wants it done, he'll do it himself when he feels like making that decision. Isn't it his to make anyway?
