Drawing on data derived from two socially contrasting primary schools in Durban, this paper focuses on how gender and sexuality feature in the teaching and discussion of HIV/AIDS. A detailed analysis of two "life-skills" lessons in the two schools shows that, despite the social differences between the schools, discussions of gender and sexuality remain muted. Discourses of childhood innocence make it difficult for teachers to provide comprehensive knowledge of sex, sexuality and gender in the primary school "life-skills" lessons. Implications for teacher training are suggested briefly in the conclusion. (Contains 2 notes.)
