José Luis García has been studying the effect of pornography on minors for four decades. He is co-director of the first Expert course in Prevention of the Effects of Pornography on Affective-Sexual Health taught by a Spanish university.

"We have to talk about porn [with minors], precisely because it is not going to disappear," he says. But he is not in favor of banning it, or trying to control access to it. "The human being has always sought sexual stimuli," says García.
