In popular culture as well as in personal stories told by many people there’s often mentions of spontaneously having sex in random places and sometimes with random people: in cars, in clubs, in bathrooms etc. But how do people do that without taking shower beforehand? Penetration is imaginable - if there’s no strong bad smell, it might be tollerable, but what about oral sex? Sounds vomit inducing.
Humans were having a lot of sex in historical situations where soap and daily bathing weren’t typical. We’re animals, you know.
But it’s also normal for people to have varied levels of drive and personal thresholds below which it is no longer worth it. I was demisexual most of my life, and I’m functionally asexual now that the mass consensus is that it’s okay to expose each other to sars-cov-2.
