After tackling same-sex marriage, lawmakers in Vermont are considering a bill that would make it legal for teenagers 18 and under to exchange explicit photos and videos of themselves, a practice also known as "sexting."

Under the current law, teenagers could be prosecuted as sex offenders if they get caught sending graphic sexual images of themselves, even if it is consensual. But, according to one recent study, 18 percent of female students say they've tried sexting.

A state House committee will hear more testimony on it later this week.

Karen Salmansohn, who is an expert on talking with teenagers about smart choices, says parents need to talk to their kids about the dangers of sexting - but she cautioned, "Don't talk to them in language saying this is right this is wrong. That's not going to get to a kid."

Salmansohn recommends warning kids that if embarrassing pictures get out, there's no way to get it off the Internet, and could affect their college and future job opportunities when recruiters search the Web. Minors can also be charged with child pornography, so sexually explicit pictures of anyone under 18 can be considered child pornography.
