Do you warn them about the consequences of taking/receiving sexual explicit pictures? It seems most teens have phones with cameras and they want to share everything. I don't think kids are educated enough on what can happen. A girl can send a topless picture to her boyfriend and now he's in possession of child porn and can be labeled a sex offender. I'm not worried about mine teens not knowing, I worked in a prison with "sex offenders". Most were, but there were 18 yr olds in for having topless pictures of their girlfriends. I make sure they know the consequences.
I think with this generation.. with even my generation.. our parents didn't think of that as something they even had to talk about. There were a few girls in my school who texted picture of themselves to their boyfriends.. and our whole school was able to watch what unfolded. So.. of course that is a topic I will touch on and stress with my daughter when she is at that age.
