I think there's plenty of social arguments for "sexual deviancy" in kids these days, from two parent households to labeling casual displays of intimacy and normal exploration of intimacy as sexual deviancy to increased ability to monitor children to hypersensitive parents labeling something as bad so teens are more likely to do it to define themselves against parents that haven't built a good relationship with their kids, etc. etc.
In the long run, though, I think American culture has a long history of demonizing anything that's close to sexuality and can get very up in arms about something that could be plain harmless or even healthy.
After all, awhile ago, when was the average age of people getting married? Sure, civilization has advanced in many ways, but have we essentially ignored REAL human nature and instincts? Have we tried to make the physicality and intimacy of being human obsolete? And by doing so, do teenagers, who have these budding instincts of human nature roaring and the pressure of society/peers, essentially reach out for this intimacy in unhealthy ways?
Honestly, I believe so, and I believe it hurts civilization and prevents it from faster and better progress.
