This isn’t true.
The internet has been around since the late 90s at the earliest…that’s when some kids started freely accessing adult content.
When I was a kid…(and I grew up unsupervised and poor with one working parent - I was free range)…porn mags were like the holy grail. I literally didn’t see one until I was about 14 and I found one in somebodies forest fort. So think about that…not only could I not find a porn mag…but the person that had one had to go hiking to “use” it.
I mean…we also had homophobic molester gym teachers teaching us health class…
