Nudity in the gym?

I read an article today in the Yahoo headlines, that indicated gyms in New York were planning to have naked work-out classes. To each his own, but I personally will be exiting to another gym. Something about sweaty naked men in knee-

socks doesn't appeal to me. Talk about the naked truth.? Also, wouldn't there be an issue with chaffing on the stationary bikes?
