I was just reminiscing in another thread about this one friend of mine when I was 10 years old whose parents didn't keep their shit locked down. Dad had nudie mags in his drawer and the older brother had even raunchier porn in his (this was the 80s), and they also had Skinemax. Sleepovers were a wonderland of an education. It should be noted that the raciest thing at my house was my mom's copy of Wifey. Later, when I was 14, I had a friend whose parents did a poor job of hiding their triple X movies. Just unlabeled VHS tapes lying around the back of the cabinet. One of my most hilarious memories was a male friend of mine watching it and laughing his ass off at the long, thick ropes of jizz that would propel out of the guy's dick when he came. I realized at that point that maybe that wasn't an accurate depiction of male orgasm. Focus: what childhood friend stood out as having a family dynamic that was startling different from your own.
