Except that there are of course many free porn sites out there, that presumably get their money from advertising. Advertising that works just as well (perhaps, better) on children as it does on adults. Also sites like xtube and such, where the content isn't actually created by any one company. Finally, almost all of the websites that do require CC payment also have 'free tour' sections, which in terms of 'harm to children' is sufficient to want to block the site.

Babies do masturbate at the age of like 1-2 years old, but I admit I hadn't seen it in a way that they could try some of the things they see, which might in the end be harmful to them.

Pre-pubescent sex can be especially harmful to young girls. Babies masturbating is irrelevant if its natural, though I have never heard of that and it seems real strange.

.... Babies masturbate? Wut?

I though the controversy was always that "children viewing porn" was always legally defined to be anyone under 18 viewing porn, not just children before puberty. Puberty tends to hit a lot before 18.

It's moderately "common".

Children that view pornographic content can end up developing some... deviant... interests, along with a large amount of pathological shame regarding those interests and, more generally, their own sexuality. They can also end up with a kind of aversion to sexual topics and in some cases even a reluctance to use certain words that have connections to sexuality (i.e. "vagina").

Please just trust me, payne.
