This book illustrates that anxieties about technology and teen girls' sexuality distract from critical questions about how to adapt norms of privacy and consent for new media. Though mobile phones can be used to cause harm, it notes that the criminalization and abstinence policies meant to curb sexting often fail to account for distinctions between consensual sharing and malicious distribution. The book describes sexting as the creation and sharing of personal sexual images or text messages via mobile phones or internet applications, including Facebook, Snapchat, and email. Challenging the idea that sexting inevitably victimizes young women, it argues for recognizing young people's capacity for choice and encourages rethinking the assumption that everything digital is public. The book critiques typical responses to sexting and argues that protecting teens, and girls in particular, from malicious peers and overzealous prosecutors may require recognizing the girls' sexual agency and choices when they sext consensually. The book analyzes the debates about sexting while recommending realistic and nuanced responses.
