Experts say an alarming number of teenagers and adults are "sexting."
A new study shows 20 percent of teens have sent nude or semi-nude photos of themselves electronically. The numbers are even higher for young adults at 33 percent.
Clinical social workers like Ed Moran say it can be a slippery slope to Internet addiction. If the photographs end up on social networking sites, it can come back to haunt the takers when it's time to apply to colleges and jobs.
"It's a form of flirtation," says Moran. "They don't see anything wrong with it at the time."
