My parents raised me out in the wilderness in a literal compound and hour from the nearest convenience store with no phone or even a mailbox.
So yeah.... I had to learn everything about the world through a little black-and-white TV in my room that had big ol' rabbit ear antenna that if I moved just right, I could get PBS from another town that had a lot of educational programming. As long as it wasn't about "evolution" they were fine with me watching PBS.
If it wasn't for PBS I would probably be dead. Seriously, that life doesn't do a person well, both my parents and a sibling drank themselves to death, others are on the way. I however, learned science, and biology, and how to read and how to do math and a host of other topics that I am going to be an eternal sponsor of PBS for. There was one special that explained sex to some degree, but was still heavily censored. My parents were too busy being high and religious to dream of having an awkward talk with their son, so I was totally on my own.
Thankfully, I learned where to find the "relationship" books on my rare ventures into town to visit places like bookstores and managed to learn a lot about sex from pilfering a book from the sex and relationship section and reading it in the kid's books section.
