Dr. Christian Jessen thinks kids should be shown "fairly aggressive" porn in schools.
The former 'Embarrassing Bodies' host believes it would be "very helpful" for a child's sexual education if they were shown X-rated footage of a guy behaving in a forceful way to a woman, because they could then have a debate about whether his actions were positive or negative.
He said: "Make kids cringe and squirm. Why not? I think it'd be very helpful in sex education to show the distinction between porn and sex as you have it.
"Most parents won't have the gumption, but at school that could be a good lesson.
"Not full-on porn, but images, for example, and then they could discuss whether that's a good thing or not.
"Get them to watch this video of a man being fairly aggressive to a woman in porn and talk about that.
"Parents would in outcry, but so what?"
Christian, 41, has urged parents to speak to their children about sexual health as "early as you can" to ensure youngsters don't turn to watching porn on their own.
He said: "It's like talking to your kids about sexual health. Do it as early as you can.
"If you make it a secretive, odd thing, that's when children turn to porn, which can lead to all sorts of hang-ups.
"You can show them what's good and what's bad. Pull up some ridiculous images and show them what can happen when it isn't used properly.
"You have to give them the chance to make an informed choice."
Christian has also called for girls and boys to be brought up "exactly the same" to encourage equality between both sexes.
When asked about bringing up children gender neutrally, he added to the Daily Telegraph newspaper: "I don't think that's so bad. If you look at the gender pay gap, there are many reasons, but one of those will be that boys and girls have always been treated differently.
"Perhaps if you brought boys and girls up exactly the same - and I have no evidence for this - then maybe this wouldn't be such a problem, because they'd see each other as equals."
