Ran across this in the news today and thought it was relevant to the discussion over whether or not erotic literature affects sexual behavior.

Disregarding the question of censorship and banning or burning books, which I do not support, I thought the relevant quote to our discussion was the sexual aid retailer who noted (at the end of the article) the increase in sales of blindfolds, restraints, whips & crops, etc. This seems to be a pretty fair bit of anecdotal support for the idea that sexual literature affects people's sexual behavior.
