No, it's not a pretty headline, but it seems to be reality.  According to a Journal of Urban Health study, one in 13 teen girls said they engaged in "multi-person sex" (MPS).  Researchers at Boston University's School of Public Health believe imitation of pornography is a leading cause.

The study found that more than half of the girls had been coerced into MPS by a boy or forced into “gang rape.” Researchers said pornography use by either partner had a primary influence. The study included girls from Boston. Economic status did not appear to be a strong indicator of risky sexual behavior.

“Girls were five times more likely to engage in MPS if they or their boyfriend had watched porn,” said Emily Rothman, of the  Department of Community Health Sciences at Boston University. “Out of those who engaged in MPS, 50 percent did things their partners saw in porn first."

Patrick Trueman, President of Morality in Media, said the following in reference to the Boston University study, "We know from scientific studies [pornography use] leads one to engage in the same activities that are viewed in the pornographic film.”

Yes, kids often imitate what they perceive as reality. Film and video appear to be reality.

The study's findings lend credence to the conclusions of Sharlene Azam, Canadian filmmaker, whose 2009 documentary "Oral Sex is the New Goodnight Kiss" reported that girls as young as 11 were attending sex parties and having intercourse with various partners.  Sharlene Azam attributed teenage hyper-sexual behavior to pornography consumption.

According to Psychology Today, a 2009 poll claimed 13-to-16 year-old boys spend almost two hours a week viewing pornography.

Parents, it is time to take charge.  Stop accidental pornography exposure for young kids and help keep teens away from the reality-altering drug called pornography.
