The HIV epidemic has had major impact on men who have sex with men in China. Most current studies view male-to-male sex as a behavioural dimension or variable affecting HIV infection, paying little attention to the socio-cultural meanings of homosexuality and their impacts on men's experiences with HIV/AIDS. This oversight has impeded understanding of the health practices of this population. Based on a qualitative study of experiences of Chinese people living with HIV/AIDS, this paper explores the complex processes in which men who have sex with men struggle and negotiate with their sexuality, family obligations, and this disease. To facilitate Chinese men who have sex with men in responding effectively to HIV and AIDS, researchers and practitioners should take into account a wide range of contextual factors including desired gender roles, family obligations, homophobia, and HIV-related stigma that contribute to current constructions of 'homosexuality' in China.
