Dr. Sheri Madigan and her research team wanted to know the prevalence of sexting behavior (sharing of sexually explicit images and videos through technological means) among youth. Between 2006 and 2016, they conducted a meta-analysis, looking at 39 different studies about sexting that included 110,380 young people from all over the world, including the United States.Studies indicate that sexting has been on the rise among teens while teen sex has declined.
