The only two forms of permanent body modification that American parents are allowed to make to their child's body are piercing their daughter's ears and cutting off their son's foreskin. Ear piercing is a relatively minor form of permanent body modification compared with male circumcision. If a girl does not wear earrings, the holes usually close up on their own. However, once a boy's foreskin is cut off, he can never get it back again.
Parents are not allowed to tattoo or scarify their child's body or to pierce their child's genitals. Piercing a boy's penis is a less severe form of permanent body modification than male circumcision.
Also, many parents make choices about plastic surgery on their kids. Kids ears stick out, and the parents get the surgery done to fix the ears.
Cosmetic surgery to correct a congenital abnormality, like pinning ears that stick out too far or removing a birthmark, is not the same as cutting off a normal, healthy part of a child's genitals without a valid medical indication.
My daughter has a scar on her forehead. We've been adviced to get surgery on it. Many parents would do the surgery. We've opted to let her decide when she's an adult. Either decision is okay.
It's great that you will let your daughter decide about the surgery. However, cosmetic surgery to remove a scar is not the same as cutting off a normal, healthy part of a child's genitals without a valid medical indication.
Because there is no medical indication for infant circumcision and because a foreskin is not a birth defect, male circumcision is more similar to other forms of permanent body modification (tattoos, body piercing, scarification, etc.) than it is to cosmetic surgery to correct a congenital abnormality or to correct an injury.
I know plenty of girls (under 18) that had breast enlargements, nose jobs, etc and other plastic surgery.
Here's a link of the regulations of tattoos and body piercings:

Some states don't allow minors to have them, while others require parental consent.
Also, pierced ears only grow closed if earings are not worn during the first few months. After that, they will remain open. I had mine pierced when I was a child, and mine will not grow closed if I don't wear earings.
While you are correct with your conclusion, which is back up by the vast body of serious science on the subject, you can easily observe there are those on this thread who refuse to deal with the reality.
I think the rampant denial is based on some form of self validation. (out side of religious reasons) The heavy denial posts are there in order to justify their own decisions. They see what they want to believe not the facts.
Nothing is going to change their minds and they will continue to mutilate the nerve endings of young boys no matter how many studies continue to show the stictly cosmetic nature of the procedure or how many adult men who have be thusly injured testify as to the loss of sensation.
People (out side of religion reasons) are clininging to the practice of circumcision because they don't want to be wrong at all costs.
