I could absolutely do with less gratuitous violence indeed. (In Stan, the violence is not gratuitous - it's shown because it is questioned)

I'm sure we could do with more sex, even for teenagers. That would be a great path toward learning / exploring / getting familiar about important aspects of it (consent, safe sex, different ways to find pleasure with it, not necessarily heterosexual sex, not necessarily sex involving exactly two people, also the fact that some people are not interested). There's no point in it being taboo. It's part of everybody's life (at the very least everybody comes from it). It just needs to be carefully handled.
