A new survey from the Pew Research Center's Internet & American Life Project found that 4% of cell-owning teens ages 12-17 say they have sent sexually suggestive nude or nearly nude images or videos of themselves to someone else via text messaging, a practice also known as "sexting"; 15% say they have received such images of someone they know via text message.
Focus group findings show that sexting occurs most often in one of three scenarios:
1. Exchanges of images solely between two romantic partners
2. Exchanges between partners that are then shared outside the relationship
3. Exchanges between people who are not yet in a relationship, but where often one person hopes to be.
"Teens explained to us how sexually suggestive images have become a form of relationship currency," said Amanda Lenhart, Senior Research Specialist and author of the report. "These images are shared as a part of or instead of sexual activity, or as a way of starting or maintaining a relationship with a significant other. And they are also passed along to friends for their entertainment value, as a joke or for fun."
