You're Lolita!
by Vladimir Nabokov
Considered by most to be depraved and immoral, you are obsessed with sex. What really tantalizes you is that which deviates from societal standards in every way, though you admit that this probably isn't the best and you're not sure what causes this desire. Nonetheless, you've done some pretty nefarious things in your life, and probably gotten caught for them. The names have been changed, but the problems are real. Please stay away from children.
