Like I get how covid conscious and dating/meet-up sites are a bit of a contradiction, but my partner and I are both immunocompromised with asthma and have followed proper covid protocol since the beginning (masking, not really going out ever, because it could kill us easily, and even if it didn't, I don't want to harm others!). It's... difficult, though. We're very social, poly people that have been effectively stuck in the best prison with the best prison mate.
Like, other people like us have to exist right, even in this hyper-individualistic hellhole? I tried grindr and tindr but, well, people lie, and it's very literally life and death. I tried googling this and came up with basically nothing.

Clean Air Clubs rent/ loan air filters and sometimes offer masks to venues and groups for events. They often advertise the events with information as to whether it's a mask required event. This is the link tree of the main group out of chicago
