6 - I hit puberty when I was 8 and didn't REALLY discover my sexuality until I was 18 (that's when I had my first orgasm, anyway), largely because of my strained relationship with my parents. A bad breakup left me anorgasmic for a little over a year after that. Things work fine, now, but I'm still really cagey around people I'm attracted to (offline), which is part of why I like things with clearer rules (D/s stuff, mostly).
