Here's a nice French film:
Chroniques sexuelles d'une famille d'aujourd'hui (2012)
Sexual Chronicles of a French Family
It's a made-for-TV type of film, low budget. IMDB rates it low but it's kind of cutesy and shows old people, young people, middle aged people living normal lives today. Catch it on Netflix. French are *still* shy about sex especially talking with their parents, of course. Parents aren't "chaperones" listening in -- just a slight change of paradigm from "not under my roof."
Just like you monitor who your *teen* is hanging out with as friends -- do you really want your teen hanging with neo Nazis? You should monitor who your teen is having close relationships with of all types. You can't control them a good parent *should* be trying to shape / monitor their choices in sex partners. You have a 16 year old (boy, girl, gay, straight, doesn't matter). Similar age BF / GF? Good. 30 year old, not good! If you aren't acknowledging they are sexual and talking about their relationships -- and are holding your hands over your ears, those types of conversations are *not* going to happen.
Of course, the above is just a film but rings true to what I've seen in France. Also good because it shows a teen making a really stupid choice (masturbating in class on a dare and recording it on his cell phone) and his school does a sensible thing -- suspends him, investigates situation, and when they find out everyone was taking turns doing the same, reinstates him. In America he'd have been arrested, maybe sent to jail, and listed as a life-long sex offender.
