With the teens in the kerfuffles I know of, I hope that it's just that they've been raised very conservatively and haven't yet taken the leap of questioning the assumptions hammered into their brains. One nonnie on FFA did look back at a teenage anti's Tumblr, and discovered that either they were a very erudite 10-year-old or lied about their age, so people who lie about their age do exist there.

As an European, the idea that teens should not be exposed to sex is headscratchy. Not forced to watch, yes, but not allowed to? Like, wanting to not have to answer little kiddies' questions, fine. But... all teens know what sex is. And, being teens, they're probably going to look at porn.

And, as someone who is still a teenager, my experiences are yours. Right down to the aceness.
