Technically, distributing naked pictures of teenage girls under the age of 18 is considered child pornography. If caught, the boys or men could face jail time and/or have to register as sex offenders -- a burden they would carry all their lives. It doesn't matter if the girl took the pictures herself, or if the photos were sent to someone younger than 18. It's still child porn.
But while the fun is fleeting, the Internet is forever. What happens when they want to get into a good university? When they start looking for a job in their profession? When they hope to play a college or pro sport or teach for a living? These pictures could haunt them forever, hindering their potential for success in the real world. The real world is not the one portrayed on TV in shows and commercials where everyone is either trying to have sex, having sex, or talking about the sex they had or want to have. (Pictured above: Actress Vanessa Hudgens in cell phone photo scandal of 2007. Sources say she "learned her lesson.")
Lingerie parties are just a symptom of a society and a generation that has lost sight of what is important. Instead of doing crunches and spending good money on ridiculous stripper outfits, teens in other eras involved themselves in social causes. Today, one of the worst problems I believe we face is the sexual abuse of women, through rape, domestic violence, and human trafficking. The line defining acceptable behavior keeps receding from the moral boundaries needed to protect women and girls. If we see ourselves as sex objects, how can we expect others to see us anything else?
