It's amazing how times have changed isn't it?
Previously I would never have put a fart in the face on the same level as being near a cough .
More to the point - rimming is not such a smart idea. I've seen to mention of the virus making its way to vaginal fluids but we do know some people like a good grope around all orifices and A2V.
I know some of them like to start with a good wet wipe down - next thing you know we spend half the punt time applying 70% alcohol to each other's privates. What that would do to vaginal health, doc only knows.
