Sexting (or "sex texting") is the sending or receiving of sexually explicit or sexually suggestive images, messages, or video via a cellphone or the Internet.
Examples of sexting include sending:
nude or nearly nude photos or "selfies"
videos that show nudity, sex acts, or simulated sex
text messages that propose sex or refer to sex acts
Why Do Teens Sext?
Many girls sext as a joke, as a way of getting attention, or because of "pressure from guys." Guys sometimes blame "pressure from friends." But for some, it's almost become normal behavior, a way of flirting, being seen as cool, or becoming popular. And teens get some reinforcement for that when lewd celebrity pictures and videos go mainstream and the consequences are greater fame and reality TV shows, not ruined careers or humiliation.
