Let’s be real for a second: Research shows that lots of young people exchange flirty texts and pictures. It’s just new technology + old habits. Unfortunately, sexting—especially when photos are involved—can easily fall under state child pornography laws, which say that possessing or sending pictures of someone under 18 engaged in sexually explicit behavior is a crime. These laws might apply to you—and you or your partner might be prosecuted—whether you’re exchanging photos one on one or passing along someone else’s photo (which is a real jerk move, BTW). This goes for Snapchat, too.
