I am circumcised.
I chose not to circumcise my son (he's 11 now.) And his younger 1/2 brother (3 now) isn't circumcised either.
When my(now ex-)wife and I first chose to have children, before we even both commited to trying to have a baby I raised the issue with her, and let her know that even though I was circumcised, I *really* wasn't comfortable with the practice - I feel that the practice is unnessary, outdated, painful and barbaric - and that the aledged "benefits", even if real, are so small they aren't worth the pain & trauma of the procedure. Most insurances won't cover the cost now anyway, and several promonant medical && nursing organizations have said the procedure is either "unnessary" or "offers little benifits". And frankly, I don't really think it's ethical to cut parts off of kids without anesthetic just for asthetic reasons, or "because it was done to me." The practice isn't really only common in the the US anyway (and most common in the East Coast) and even here the number of children subjected to the procedure is falling rapidly every year. And I wanted to let my son have control over his own body.
My ex-agreed with me, and said that choice should be mine anyway - but later when she researched it herself she said she wouldn't have given me permission knowing what she learned.
When she (briefly) re-married and had another son, she told his father (who was also circumcised) she didn't want ot done and why - he agreed.
(Now they're divorced, he left and a couple of years after that she and I got back together, so I help raise that child too, and treat him as if he were my own - and I think it's good that he looks like his big brother.)
