Your kid looks at porn. Now what?
Here's what we know: All children are sexual. That means they have sexual feelings and thoughts. Naturally, six-year-olds don't think about intercourse, and thirteen-year-olds can't imagine the subtleties of mutual arousal and satisfaction. But every human is born a sexual being. How parents deal with their feelings about their children's sexuality will shape how they feel about, and what they do about, their kid looking at porn. So how do you, Mom or Dad, feel about your kid masturbating? That is, after all, why he or she looks at porn more than once or twice. If you can't handle that, the kid's use of porn will of course be unacceptable - but beside the point. Whether it's about kids' use or adults' use, too many conversations about whether porn is harmful to users or society is really about the unacceptability of masturbation. If that's your position, be honest and say "I don't want my kid masturbating to porn because I don't want my kid masturbating."
