pornography is a public health hazard leading to a broad spectrum of individual and public health impacts and societal harms
Pornography, in itself, isn't a public health hazard. Not educating teenagers about the realities of sex is the health hazard.
Talking to children in an open, frank, non-confrontational way about sex is the best way to improve sexual health.
Sweeping sex under the carpet and trying to hide porn will only lead to children finding out about sex by trying. And that's precisely what we want to avoid!
