I got out an audio book on CD from the library entitled '100 Strokes of the Brush Before Bed' by Melissa P. (real name Melissa Panarello).
Ok, so it was laden with very very BAD sex. And the writing left something to be desired (so did the reader's Italian accent which sounded exactly the same as her Middle Eastern one...).
She has a series of ugly encounters and affairs with everyone from a professor, five guys on her birthday, a married man, college students and a woman... I read a review of this book which called it depressing. So said by someone who has obviously never felt as though they were reduced to a sex object, and who doesn't even go half way to understanding the emotions and major issues of life brought up in the book.
Some of the situations horrified me with their unimaginable pain and degredation, and some of it reminded me of my own experiences. I feel really sad for her (it is thought to be semi-auto-biographical, the author is a year older than me and her eploits take place between her 14th and 16th years, btw). But I loved it for one reason and one reason only: even though she'd managed to haplessly screw her way through more than half the characters in the book, she eventually discovered an unconditional love.
I guess I am always drawn to stories where you get another chance to be accepted for who you really are and to not be judged by your past, no matter you have done before.

I like this interview with Melissa P. the best:
