I don't really see what all the news is about, as it's just a part of puberty. It's only "bad" because society tells us it is, with no real negative impact to hold over it. There's not much difference between visualizing it in your head and watching it on a screen. I'm not saying we should hand out Playboy to 12 year olds, but that we shouldn't condemn it if it's indeed uncovered. It's all just part of discovering your own sexuality, and I believe it should not be repressed. Let's say you drive your car on a muddy road, and inadvertently get it dirty. Would you then park that car in your garage to shelter it? No, as the damage is already done. The car's functionality has not changed, but it's still affected by the societal norm that says that it should be "clean".
