It's not chopping off the dong, you fools, it's a piece of skin. Doesn't touch the tip or anything, so it's not like your sensitive bit gets harmed at all.
I personally like the look of a circumsized one better, but uhm... Whatever. I wouldn't mind either way, really... Just... Keep clean. Please... I've heard tales about "dick-cheese" and I'd rather not experience any for myself... *Shiver*
Now female circumcision is just completely wrong... You may think it's a double-standard here, but really it's not. They cut off all the skin on a girl's downstairs, including the really sensitive part. (Clitoris) That's like someone cutting off the tip of your thingers there, guys. Ouch.
