In 2009 Dr. Phil spoke about the topic "Sexting". Sexting is sending nude pictures via text message (using cell phones).
This topic is not just on Dr. Phil unfortunately, it's becoming a common practice among teens, 20% of teens polled in a national survey.
Besides loosing a persons reputation the teens that participate in this are also facing felony charges for being involved in child porn and being registered as a sex offender---which will never come off of their records.
