I don't remember even being interested in women sexually till around 10th grade. Then locker talk begins and you start to think "great, now I have to have some story or some competing number". I have a strong suspicion that sexual experience (not just experimenting, but many partners) in elementary/middle school is due to a relationship with one's parents or some traumatic event as a child. Many people start to experiment at a young age but when that turns into 10+ partners before HS it seems to be a real issue. Most men would be proud (and this guy's case very proud) to have a high number compared to their peers despite the dangers. I'm not saying sex is bad or to have a high number of partners is bad, but more so that extreme sexual experience during an important mental development stage may be signs of other issues. I am surprised (hrm, surprised has 2 r's... oO) that this guy seemed pretty sure that it was simply because he liked having sex. Then again, many people don't think much further than that.
