The problem you're describing is exactly what we need to solve, instead of introducing another censorship/citizen tracking measure. Kids should be learning about their own sexuality, about these urges, how to handle them, how to not handle them. The main reason they're reaching out to that is the obvious, unescapable growth phase AND complete lack of support from parents, teachers and society in general. On one hand we're making sex and sexuality the ultimate taboo, pushing kids into handling these issues completely alone, on the other we're pouring sexuality into everything around us, including car tires sales. And then we try to censor/track all citizens in name of 'think of the children', what's a completely and utterly broken and least effective solution to the symptoms, not the disease.
