While it is likely to be because I come from a country/culture where porn isn't considered to be an issue, I would appreciate an explanation as to why "cut[ting] down exposure to this type of material" is desirable at all. When kids decide that they are mature enough to consume such content, I don't think it should be turned into a controversy. Personally, I decided to wait until I was seventeen to explore that part of the web, as I matured fairly late. I never "stumbled upon" sexual content by accident, despite making heavy use of the Internet. If people, regardless of age, are looking for sexual content they will find it. If they want to avoid it on the other hand, "accidental exposure" shouldn't be an issue either. There is no need to police the Internet.
