A new study of Dutch teens finds that few of them frequently engage in risky online activity related to sex, such as sending naked photos to strangers and searching for sex partners, but those who do are more prone to have casual sex in real life. Jeff Temple, a psychologist and an assistant professor UTMB who studies teenage sexuality, said the study provides “more evidence that the boundary that separates offline and online lives is becoming increasingly blurred.” He added: “It's important that pediatricians and other health-care providers need to focus on online behaviors as much as offline behaviors as they're beginning to look like one and the same.”
