According to a controversial new study, more than 7 percent of teen girls have engaged in group sex. Of those teens, more than half said they were pressured to take part, and 43 percent said they were forced. The study was relatively small: Just 328 females between ages of 14 and 20 were interviewed in community or school health clinics in the Boston area. Still, the numbers are fairly alarming. For girls who had participated in one of these group sex experiences, the average age was less than 16. In addition, researchers found there was some sort of link to pornography—that perhaps girls are being forced into these acts based on what their partners had seen in porn. (New York Daily News)
