Interesting idea, but I'd sure be reluctant if I were a man

NYC Eyes Circumcision Push to Fight AIDS

I'm generally in favour of circumscision. I think it has good health benefits, etc. I've known a child who wasn't circumscised as a baby who had to be a few years later due to a condition, and I suspect it was fairly traumatic for him. But there's even more of a difference between circumscising an infant and asking a grown man to go under the knife and change the physicality that he's always known. I don't know too many guys who would volunteer for that, even if it could help prevent HIV transmission.

Still, anything's worth trying, I suppose.
