Expanding outward from previous scholarship on gender, queerness, and heteronormativity in children's literature, this book offers fresh insights into representations of sex and sexuality in texts for young people. In this collection, new and established scholars examine how fiction and non-fiction writing, picture books, film and television and graphic novels position young people in relation to ideologies around sexuality, sexual identity, and embodiment. This book questions how such texts communicate a sense of what is possible, impossible, taboo, or encouraged in terms of being sexual and sexual being. Each chapter is motivated by a set of important questions: How are representations of sex and sexuality depicted in texts for young people? How do these representations affect and shape the kinds of sexualities offered as models to young readers? And to what extent is sexual diversity acknowledged and represented across different narrative and aesthetic modes? This work brings together a diverse range of conceptual and theoretical approaches that are framed by the idea of sexual becoming: the manner in which texts for young people invite their readers to assess and potentially adopt ways of thinking and being in terms of sex and sexuality.
