The study out of the University of Southern California in Los Angeles shows that about a third of students who carried a smartphone with Internet access, and nearly half of those kids said they were sexually active. Among teens who did not use a smartphone, only a third reported having sex. However, for psychologist Jeff Temple, smartphones may actually prove to be an excellent tool for educating kids about sex and sexual health. Temple says there are a few programs out there already, but it is too early to tell if they are effective. “But anything we can do to reach kids in person or via social media is something worth trying,” says Temple, an assistant professor at UTMB who has studied the practice of sexting among teens.
