Yes, but then again, definitely no.
A few decades ago we used to make endless stupid jokes about "homos" and "queers" but the idea that the guy at the next locker, or the gym teacher who made sure you took a shower, might be gay, was pretty far from anyone's mind (which made life just a joy for the gym teacher who really did have a taste for pedophilia). Now there's a recognition that homosexuality is common and pretty much normal, gay couples can get married in more and more states, and the "don't ask don't tell" policy in the U.S. armed forces just seems to be irrelevant. But at the same time, there have been enough stories about pedophiles--those priests did the most damage--that young people are told to be constantly on their guard, that they're all potential victims. So now we're afraid that everyone might be thinking of making a grab for anyone, and kids are all protecting themselves from mostly imaginary exploitation. It's not so much homophobia as paranoia, the perceived need to defend yourself all the time, and never let anyone have a way to take advantage of you. It's unfortunate that nudity is seen as being the first step toward exploitation, but people tend to look for simple ways to solve complicated problems, and they think that by keeping their clothes on they'll be protected. It's very sad.
