Condoms, PrEP and undetectable viral load are key combinations to help you stay safe. Here are some other methods you could also use to reduce risk.

These strategies have varying degrees of effectiveness and their effectiveness is based on specific conditions that must be met, such as knowledge of your HIV status and that of your partners. Risk reduction strategies may include:


Serosorting is unprotected anal sex between gay men of the same HIV status. You have to know your own and your partner’s status for serosorting to be effective. Just assuming it is the same is not enough.


This is when the top pulls out before cumming. This strategy is relatively ineffective and doesn’t reduce the risk to the top very much at all.

Neg Top / Pos Bottom

This is when the HIV-negative guy tops an HIV positive-bottom. Topping is less risky than bottoming but still includes risk of HIV transmission. It also includes risk of STI transmission from top to bottom and vice versa.

Negotiated safety

This is a particular kind of relationship agreement where HIV-negative partners in a regular relationship disclose their HIV status to each other, discuss risks and agree to repeat HIV testing before having unprotected anal sex. For more information see Our Team.
