Add Oklahoma to the list of states reviewing child pornography laws and considering possible changes to take into account the surge in "sexting" among teens. Like others across the country, some Oklahoma legislators agree that 10 or more years in prison is excessive when the individuals involved are in a consensual relationship, even if one or both happens to be a teenager.

Sexting is generally defined as the production and transmission of sexually explicit images or videos using cellphones. By some estimates, as many as 1 in 5 teens has taken and distributed a nude photo.

Here's a warning to parents and teens about the potential spread of sexting photos: Police in Emmaus, Pennsylvania are investigating how nude photos of high school students wound up on an unnamed pornographic Web site.

According to reports, the photos were taken by the teens themselves and shared with classmates. It's not clear right now how the photos wound up on the adult Web site, or how they were discovered. Police believe, however, that the photos were on the site "for some time."

A recent joint survey by MTV and the Associated Press reports that one-third of teens ages 14-24 have sent or received a "sext" message.

Roughly half that number (15 percent) have taken naked photos or videos of themselves, and shared those photos with someone else. In ten percent of those cases, the photos or videos are being shared with someone that the teen only knows through online contact.

This summer, Florida joined the growing number of state that have changed their laws to address the growing sexting issue. The legislature amended its obscenity statutes by adopting Section 847.0141, entitled "Sexting; prohibited acts; penalties."

Florida is one of the first states to draft a legislative definition of "sexting": "to transmit or distribute to another minor any photograph or video of any person which depicts nudity." That's somewhat narrower than the colloquial definition, which includes explicit text messages or images/videos of sexual activity.
