What does a safe environment mean? And why let kids experience that kind of content?
They will experience it eventually, at some point in their lives, whether as kids or as adults. Giving them a controlled way to experience these things can help them fortify themselves better against their worst consequences. It’s the same approach taken by many parents regarding cigarettes and alcohol. Warn the child against it, but if they are determined to try it, it’s better that they try it together with the parent, than alone or with friends, where they can binge, get carried away, be harmed by it, etc.
The mystique and the thrill of doing something forbidden plays a huge role in driving kids towards these things. And the adrenaline of having done something forbidden can actually reinforce the behavior and make it even more addictive. However, if there’s the option of doing whatever in a safe manner and supervised, then kids tend to not consider it so attractive anymore. It’s something to experience, sure, but there’s no longer a strong urge to over-indulge. And whoever is supervising them gets the chance to help them through certain emotions about the experience, rather than let them deal with it alone, whether it’s porn, horror, gore, violence, drugs, alcohol, cigarettes, etc.
I’m not saying let the kids experience anything willy-nilly, just because it’s futile to stop them. I’m saying let them have an option to experience it safely, with someone who is going to be able to help them comprehend its consequences. For example, with porn, it’d be helpful if they are informed about how exploitative sex work can be, how certain porn is not made with consent, or even used as sex education.











Pornography is used in sex education in some countries. Not very widely, and usually at the later stages and ages, but still used.
I’m not an expert in sex education, so I’ll refer you to this article as a jumping off point: https://www.apa.org/monitor/2021/03/teaching-porn-literacy

EDIT: Just so we are clear, since I saw your edit after answering, sex education isn’t just about practicing safe sex. It’s also about dealing with sexuality emotionally. Including being able to assess sexual content (in regards to consent, morality, etc), body positivity, avoiding feelings of guilt regarding sex, sexual orientation, sexual preferences and sexual content, and identifying signs of bad sexual tendencies and helping to overcome them (e.g. linking violence and sex). In that regard, sometimes letting kids view certain porn can help to reinforce these lessons. Especially in regards to sexual orientation and preferences.
