It seems more and more the spread is attributed to airborne spread (vs. touch, surfaces) so masks could be a safety factor for some fun. I mention in a post above I’m considering meeting a regular for a limited, no oral/masks off meeting, just some touching and he would bottom doggie style - probably safe but not 100%.
Sanjay Gupta had a bit on CNN the other day saying wearing masks around positive people gives you a 3% risk of infection, without masks was twenty-something%% chance sorry I can’t remember that higher exact number, can’t find the link!
