Ever since we released the report on our "Sex and Tech" survey last month with CosmoGirl.com, my fellow Campaigners and I have been answering questions from hundreds of reporters who want to get to the bottom (so to speak) of the "sexting" craze.

Our survey found that about 20% of teens have posted or sent nude or semi-nude photos of themselves; and about 30% have received such images meant for someone else. About 3/4 of the teens in our survey acknowledged that this kind of thing is risky and could have negative consequences.

But they're doing it anyway. And now the consequences seem to be more serious even than future embarrassment. Today's New York Times notes the latest example of teens across the country who are being charged with dissemination and possession of child pornography, even when they're sending photos of themselves. That makes for a murky legal situation, and a really scary one to find yourself in.

Countless reporters have asked me if we should just make sure teens only have cell phones without cameras. Have you tried to buy one of those? I'm not sure you can anymore. Besides, it's not the phone's fault. Instead, we need to teach teens how to use technology in a smart and safe way, and how to make sure that something done on a whim or a dare doesn't cost them their futures. Parents remain the most powerful force in teens' lives—and while most parents don't feel like they're experts at technology, they are still experts at being parents.

What would you tell your teen? Have you asked your teen if they know anyone who's done this? Tell us you thoughts and find tips for parents and teens on the Sex and Tech page of our Web site.
