They don't give their names, but viewers can see their faces plainly and what these teens are saying is shocking parents.
Pre-teens and teens are engaging in sexual activity at an earlier age.
"I ended up having sex with more than one person that night and then in the morning I was trying to get morning-after pills," one of the girls said. "I was, like, 14 at the time."
It's just one of dozens of stories from teenage girls in a new documentary by Canadian filmmaker Sharlene Azam [pictured] 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.
"If you talk to teens [about oral sex] they'll tell you it's not a big deal," Azam said. "In fact, they don't consider it sex. They don't consider a lot of things sex."
