The internet is an open book! Everything you post Google and the other internet stalkers, keeps a copy on file. So, talk to your children about their post and share because some people love to share private moment.  One thing I never liked and never did was take nude pictures. Since I know myself, standing in front of the mirror looking at front, backside and the cookie for my view. Any way no man ever asked me to take a naked picture. If I was asked, my response would be, “You want to control me. What kind of a perverted shit is that?
