A while ago I came across this article in the 7 September 2010 issue of Salon.

The smart Dutch take on teen sex
Despite parents’ allowing romantic sleepovers, the Netherlands has one of the lowest youth pregnancy rates
by Tracy Clark-Flory

I’m not going to reproduce it here as it’s available online. The article also references this study by Amy Schalet. I commend you all to go read both for yourselves. Amazingly Clark-Flory (an American) actually recognises that the Dutch have their attitudes to teen sex right and the Americans don’t. Which is what I’ve been saying for years. Society, especially politicians and the religious please note!
