A bit of a dismissive post, Steve.
Surely the problem is that unlike when most of us were growing up when porn was top shelf material and of a very tame nature, now children are exposed to much more graphic content which is much easier to view, and some of which is going to cause unreasonable expectations as to what is possible, and more importantly will confuse issues around what is considered consent. It is a real problem for those involved in trying to give a realistic portrayal of sexual intimacy to teenagers (and younger).
