I am totally with you. If it isn't for religious reasons.
It is not my right to lop off tissue that is not mine, that is not diseased. If he wants it done later, it is HIS CHOICE, and not mine to make. I also did not get my daughter's ears pierced until she wanted it.
And it CAN be compared to female circumcision. On the cleanliness issue- my little girl would be so much "cleaner" if we lopped off her labia to make it easier to clean. If it was done in the Dr. office in a clean environment, why not?
Intact penises are easily cleaned, with regular bathing. Males have a greater risk of breast cancer than penile cancer with an intact penis.
If the reason is to "look like Dad", less than 15% of males even know if their dad is circumcised. About 1/2 of today's males in the US are NOT circ'd- it isn't going to be that big of a deal later.
After doing research, realizing that it is no longer routinely recommended by the American Academy of Pediatrics, and that the US is the only country that routinely practices it, and learning more about all the nerves involved, I realized NO WAY. It's barbaric.
