Sexting has arrived. The days of passing notes in class are a thing of the past and young teens 

The texting and camera features available on most phones, and a permissive society, have lead to 'sexting.' What is sexting you ask? It's exchanging sexual images on cell phones.

Miley Cyrus is the most famous to have been involved in "sexting" when racy images intended for her boyfriend at the time were leaked by someone who hacked her phone.

Then there was Vanessa Hudgens and Antonella Barba. And most recently, Cheetah Girl Adrienne Bailon.

Experts say "sexting" is becoming an all too common practice for many teenagers, who often think it's no big deal to send racy photos via email or text. Many consider it nothing more than sending a flirty note.

According to researchers at Rochester Technology of Institute almost one-third of teens in grades 10-12 have sent or received sexual content online and they utilize cell phones.

For children in grades 4-6, that number is one in ten. See a video here.
