Coach-athlete sexual relationships (CASR) constitute ethical, behavioral, social, and emotional quandaries that are rarely addressed openly. Most of the current body of research in this area focuses on coaches' sexual harassment and abuse of children and female athletes.In the present article we discuss legal CASR and adopt a coach perspective. As dual relationships, CASR blur the boundaries between professional roles circumscribed (usually) by ethical codes of conduct and private spheres of love and desire. We explore the problems associated with the limitations of dichotomous right/wrong ethical decision making and discuss additional ways to understand these relationships, accounting for coaches' and athletes' well-being, performance, gendered sexual agency, power, ethical dilemmas, sport policy, and legal implications. Our discussion raises questions about how to open up dialogue and transparency regarding CASR and how to facilitate functional, healthy coach-athlete relationships. Finally, we provide implications for future research that include legal and consensual CASR and advocate transparency, open discussion, and coach education about CASR dilemmas.
