You are wrong. Do some of your own research and you can find the same. Of course there is some growth of the skin, but if the person performing the circumcision makes a mistake then the skin will not keep up with the growth of the penis during puberty.
I don't want to post any real images that I found because I don't know who they belong to or if they would approve, but here is an illustration:
You can find real examples of this on this site.
Also, I'm not anti circumcision. If an adult wants to get it done go for it, I don't care, like I said its safer for an adult. Stop doing it to babies that have no choice.
Do you have an argument for why its better to do it to an infant than an adult who actually has the ability to choose?
