It's just one of dozens of stories from teenage girls in a new documentary by Canadian filmmaker Sharlene Azam that aims to shed light on the secret, extremely sexual lives of today's teens. After four years researching for the documentary , Azam told "Good Morning America" that oral sex is as common as kissing for teens and that casual prostitution -- being paid at parties to strip, give sexual favors or have sex -- is far more commonplace than once believed. They don't consider a lot of things sex. Evidence of this casual attitude may be seen in the fact that more than half of all teens 15 to 19 years old have engaged in oral sex, according to a comprehensive study by the Centers for Disease Control's National Center for Health Statistics. In the documentary, "Oral Sex Is the New Goodnight Kiss," girls as young as 11 years old talk about having sex, going to sex parties and -- in some extreme situations -- crossing into prostitution by exchanging sexual favors for money, clothes or even homework and then still arriving home in time for dinner with the family. The girls are almost always from good homes, but their parents are completely unaware, Azam said.
