The effect of pre-exposure prophylaxis (PrEP) on negotiating casual sex between gay men: disclosure, assumptions, and communication.

Background: The disclosure of HIV status and pre-exposure prophylaxis (PrEP) use can be important in the negotiation of safe sex. With the rapid uptake of PrEP in Australia, norms and expectations about discussion and disclosure may have changed. Methods: We explored the disclosure of PrEP use, HIV status and communication with sex partners by HIV-negative gay men in Sydney, Australia. We conducted semi-structured interviews from October 2017 to May 2018 and analysed data using a codebook thematic analysis approach. Results: Participants had a variety of expectations of what they should tell their partners and what they expected in return. For some participants, PrEP had negated the need for any discussion about HIV. Many participants assumed their partners would find information about their HIV status or PrEP use on their online profiles or that partners would ask, if necessary. Conclusions: Building a stronger, shared understanding among gay men that disclosure and discussion no longer automatically occur before sexual encounters may be useful.
