Everything and as early as possible. I got the bulk of my information from my parents, especially the night I got period. That was my first real sex talk. I was 10, I think, spending the week with my dad and I got my period. Clueless, he called his best friend to take me "shopping." Later that night, we were laying in bed and he began the inevitable. Thinking back on that day, it sucked, but I'm glad it happened; I'm glad I got started early. Personally, I just need my parents to be cool about it all. I mean, they trust me enough to know I'm not out sexing it up, but we've got the relationship that when it happens, they'll know. Parents sometimes just need to sit back and be a friend, yet an adult to their teens. That's what I love about my parents. =]
