This is so a Lori topic, but I found the article while reading other stuff on the EW website.
So, let's all play... what books were particularly racy or "dirty" that you read when you were a kid? And to give this topic some actual legitimacy, why do you think books that explore sex or sexuality are still so stigmatized in today's society?
Oh, and as for me, off the top of my head, I remember being particularly fascinated by the following:
CLAN OF THE CAVE BEAR (and sequels) by Jean Auel
FLOWERS IN THE ATTIC (and ALL the sequels) by V. C. Andrews
HAWAII by James Michener (which I still love to this day; it's a great book)
