Abstract
Globally, there is limited research exploring the positive role men play in reducing HIV vulnerability or in the care and support of women living with HIV.

Findings highlight that some HIV negative men in heterosexual relationships are resisting hegemonic masculine norms they see as harmful and are embracing caring masculine identities as they seek to support their HIV-positive wives. We suggest that understandings of masculinity in the context of the HIV epidemic in PNG should be broadened from simplistic discourses and representations of men as largely uncaring and violent to incorporate deeper understanding of how men can and are embracing caring masculinitie
