Few things get under my skin as fast as seeing blame placed on books, role-playing games, movies, magazines. Men don't turn into rapists because they subscribe to Playboy. The underlying root problem has to be there to begin with. Sure, when I feel that she is mature enough. I also let my mother read them, and my younger brother, and it doesn't bother me at all.
Maturity is relative.
And that, I must confess, has on the occasions it's happened, only led me to write even naughtier stories than the one to which the person was referring. Petty, yes, but I might as well own up to it. Of the erotic fanfic I've written, nearly all of it has been based on animated characters, mostly from Disney. And nearly all of it has followed up on what I personally read into the source. I believed that the look Nala gave Simba was laden with come-hither sensuality.
