The Question: 

My teenage daughter just started dating someone. I know she has the app Snapchat and she's told me that it's their main mode of communication when they're not together. I know little about the app but from what I've researched, I know that it is a common platform for nude-sharing. My daughter is underaged and I think she's learned a little about the danger of sharing nudes when you're under 18 at school, but I've never had a conversation with her about it. I'd love some advice for how to start a conversation around this uncomfortable topic.
