I received a text from my 16 year old daughter's friend informing me that there were explicit pics of my daughter going around the school. She also informed me that my child has been having sex with multiple boys at school. I don't even know when or where she would be doing it! She doesn't really date and we keep pretty close tabs on her whereabouts. But, that's neither here nor there. The pictures are what have me completely devastated. I haven't seen then, but I have no reason not to believe the friend. I am at a complete loss. I feel like a complete failure as a parent. My husband and I have a very open (we thought) relationship with her. I have been struggling on how to approach her about what I've learned. I know I'm supposed to be calm, not degrading, etc. Please, any suggestions?
