I never had the talk. My dad was always (and still is) very introverted, and never likes to discuss anything that makes him uncomfortable. My Mom, she never really engaged in uncomfortable talks with me because it's really awkward for a mom to talk to her son about sex and penis things. She left that for my dad to do, which he never did. I had to figure it all out on my own.
Come to think about it... my parents never really engaged me much in those "life's lessons" kind of things. You know... the "How to's" of life. Sex, shaving, changing the oil/brakes on my car, cooking, laundry... None of that kind of stuff. It's all shit that I had to figure out on my own. Mostly trial and error... except the oil/brakes... that was one that I knew that trial and error may end tragically so I did my research and looked at the process before disassembly. The sex though... for a long time I thought my penis squirted milk (obviously that ended when I tasted it... lol., j/k, I learned otherwise in sex ed.) I thought this because boobies make milk and make the baby grow, so a mans milk goes into the woman and a baby grows. Sound logic, right?
Hmm... This explanation might just be the epiphany to explain my psychological issues...
