{The "idea" of sex with children pre-exists the printing press.} Heck, in some areas of Ancient Greece, there were something like seven "levels" of "love." One of the "lowest" was that between a man and his wife. The highest, 'ideal' of Grecian love was an adult man with a boy on the cusp of puberty. So, no, it is something that has been around for a long, LONG time... As have it's unfortunate side effects, I suspect.
