Signed, Freaking Out!
I spoke with three families in one week about this same issue. Teenagers have so many more options to explore their sexual selves in ways that can really come back to haunt them. And they don’t have the cognitive development to really understand the long term consequences of texts and pictures that can be saved, forwarded to friends, and photographed in a screen shot and uploaded to all kinds of social media sites. I had a 14 years old girl in my office who was humiliated by a topless “selfie” she took that ended up on Facebook.
