In many South African communities, socially constructed masculinity norms that promote unequal gender relations and high risk sexual behaviour are key contributing factors to HIV transmission. Following a qualitative approach, using in-depth interviews, this study engaged graduates of the Tavern Intervention Programme (TIP) in Gauteng to explore and describe their perceptions of traditional and modern masculinities, as well as their experience of the TIP. The findings indicated that, while there are differences between traditional and modern men, several masculinity practices, such as unequal gender relations, inconsistent use of condoms, infrequent accessing of HIV testing opportunities and entitlement to multiple partners endure as potential barriers to HIV prevention. Additionally, peer groups reinforce and reward HIV risk behaviour among modern men. Participants did, however, report changes in perceptions and behaviour regarding gender relations and HIV prevention as a result of their participation in the TIP. This study concluded that the role the TIP played in providing these men with an environment where alternative masculinity behaviour could be explored and supported was of particular value in terms of changes in their perceptions of masculinities, gender relations and HIV prevention. / Sociology / M.
