Also, I'm sick and tired of "child porn" including 14-18 year olds. It isn't child porn. They arn't children. They are teenagers. Some of them have been having sex for years. It should be a different offence to posses and it should not be an offence to posses if you were in a loving relationship (and similar in age, a 14 year old and a 16 or 17 year old, not a 40 year old and a 14 year old).
You know those dirty letters you got from your sweetheart when you were 17? Sexting is the same damn thing.
