National Geographic was my first porn. What was yours?

I'm not sure why my mom subscribed to National Geographic magazine - she probably got them for over 20 years. We had stacks and stacks of them in our basement (my secret lair) when I was little. When I was probably 11 or 12, I started finding the naked black titties of the African girls that so frequently adorned some of the pages of those magazines. I should have cut them out and kept a collection, but I didn't think of that at the time. Nobody else read the stupid magazines anyhow - just me. My mom never found the time, and my little sister certainly didn't care about them! What was your go to before real porn??
