I think that Lonely_Heart and I were not talking about porn-like sex or anything related to the media coverage of sex. We were talking about the normal sex lives of young people who date without cohabitation. In such scenarios, normally, each time people hang out, they have sex, without exceptions, unless they hang out in the company of other people. This has always been my experience and I neither watch porn nor watch TV so my level of exposure to media is at zero.
