Teens are becoming increasingly sexually powered - to them, sex, oral sex, and prostitution is as serious as a goodnight peck on the cheek.

A documentary by Canadian filmmaker Sharlene Azam revealed how sexual today's teens are, behind the knowledge of their parents. After four years of researching for the documentary, Azam tells "Good Morning America" that oral sex is as common as kissing for teens, and casual prostitution is more common than anyone would think.

One of the girls interviewed in the documentary says, "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. I was, like, 14 at the time."

"If you talk to teens [about oral sex] they'll tell you it's not a big deal," Azam said. "In face, they don't consider it sex. They don't consider a lot of things sex."

The shocking truth is, more than half of all teens aged 15 to 19 in the US have engaged in oral sex, according to a study by the Centers for Disease Control's National Center for Health Statistics.

The documentary, "Oral Sex Is The New Goodnight Kiss" tell of girls as young as 11-years-old talk about having sex, going to sex parties and even getting involved in prostitution in exchange for money, homework, or clothese.

Many of these young girls aren't even necessarily from poor families. Just the idea of getting money in trade of their bodies makes it seem worthwhile to them. "Five minutes and I got $100," a girl said. "If I'm going to sleep with them, anyway, because they're good-looking, might as well get paid for it, right?"

The scary part is, parents aren't even aware of what their daughters do, not that their daughters would want to tell them anyway. It's sad to see young girls trade their bodies for something as cheap as money, clothes, homework and relationships (Parents are encouraged to be aware of their teens suddenly getting new clothes and bags and etc).

"There's a lot of social pressure," one girl says. "Especially because of our age, a lot of girls want to be in a relationship and they're willing to do anything." Many of them "resort to a casual thing, no strings attached," making sex perfectly fine to them.

However, Azam says she thinks the "no strings attached" romances could be a defense mechanism against disappointment in the relationship sector. Girls want to be able to hook up like guys and not have a care in the world. "But unfortunately," Azam says, "They do care."
