Some HIV-positive guys may decide to only have sex with other guys who know they are HIV-positive. There are a few things to keep in mind about sero-sorting for poz guys.
For poz guys, only sleeping with other poz guys can be a relief, since it’s less likely you’ll have to deal with 
misunderstanding and stigma, or in some cases the worry about the transmission of HIV to an HIV-negative guy. Maybe you’re waiting to get linked to treatment, or in the middle of switching medications, so you’re not undetectable right now. Some guys are willing to accept the possibility of getting other STIs if they can have sex without condoms.
Two guys who know they have HIV choosing to have sex with each other is a reliable form of “sero-sorting” because HIV status is known to be the same.
Still, there are a few things to keep in mind if you’re an HIV-positive guy who is sero-sorting:
- Getting tested and treated for STIs regularly can help to reduce rates of STIs in gay men’s sexual networks.
- STIs are worth avoiding, which you can do by using condoms. The rates of STIs like syphilis are a big problem right now for gay men. They are particularly high among HIV-positive guys. Some STIs can be hard to manage, especially if left untreated.
- Talk to your partners — it’s possible that one of you is getting treated for an STI or that something about their approach to sexual health has changed.
- Even if you’ve hooked up with a guy without using condoms before, you may feel differently later on. You can let him know that you’d be more into it using a condom this time.
