Mirroring increased cultural and disciplinary attention to sexuality, many introductory sociology textbooks have begun to include coverage of the topic. Our study first assesses the extent of textual coverage of sexuality in a sample of 38 introductory textbooks published after 2000. Secondly, we focus on 14 textbooks with a sexuality chapter and/or textbooks with more than the average textual coverage of sexuality. We find that the emergent "core" of the sociology of sexuality centers on sex research, historical and cross-cultural trends in sexuality, media representations, gender and sexuality, homosexuality and society, and sexual violence. These textbooks vary widely in their attention to the intersection of race, class and sexuality and theoretical applications. We find lingering heteronormativity, homogenization of homosexuality, and problematic representations of non-normative sexuality within the chapters. We conclude with comments on the relevance of these findings and offer some suggestions to ensure that coverage of sexuality better reflects scholarship and discourse within the discipline.
