Paul Sheehan had an interesting article, titled We live in a sexual twilight zone, in last weekend's Sydney Morning Herald. He starts from considering two current films, Towelhead and Candy Girl, which have themes of sexuality in young teenage girls and young women, and Bill Henson's photos of naked pre-teen girls which caused a furore in Australia recently (Sheehan defends Henson).
He quotes sources indicating a high level of sexual interest and fantasies in young women and even young teens. For example, one Australian study shows that almost all children had seen internet porn by the age of 15, and for most of them it was their primary source of information on sex. A third of 13 year old girls have had sexual experience. (However the study was small and almost certainly not representative.)
He doesn't blame the internet, but considers "it may have created a more accurate mirror of who we collectively are as a society, in conflict with the laws and conventions we have constructed." That's a scary thought. And he concludes with this sobering idea:
"Frankly, it is our culture saturated with debt, consumerism, two-income families, one-parent households and a coarsening public domain that has done more to truncate the innocence of youth than random perverts, a reality we have barely begun to acknowledge."
