Does it make sense to teach this to children? Just like "Smoking isn't good for your health."(which I believe worked for me) you could teach "Porn isn't good for you, if you want to enjoy sex."
I think the problem is our society's denigration of sex. We see it as consisting inherently of that mix of thrill and shame - when you're a teenager growing up in America, you're told to feel that way about any nudity, never mind penetration. So you come to associate arousal with this guilt - you never experience the one without the other - and then when you're looking for something to turn you on you're already feeling guilty, and there's a part of you that wants to. So you step a little deeper into the pool of fetishes, find something a little stronger (and I'm pleased that the author's actually given some realistic examples here), something that makes you feel guilty and ashamed and is all the more erotic for it. But the interest half-life for porn is tiny; what was dangerous boundary-pushing last week is pedestrian today. It's a feedback loop, one that can only possibly end somewhere unpleasant.
The author's already found the solution - we need to separate sexuality from guilt and shame, to be able to feel aroused and wholesome at the same time. But it's hard to do that after you've already fallen down the spiral. We need to make our children's first experiences of arousal feel natural and wholesome - which means more openness, more embracing of sexuality in artforms that are going to portray it positively. But that's a hard sell to middle America.
