The first statement there is simply not correct. There may not be any visible feces there, but there are feces germs.Pretty amazed that there's some guys on here that think licking a chick's asshole involves feces.
You don't lick every asshole you come in to contact with. And there is such a thing as soap and water. Just like anything...The smell test comes into play .
When you're being "picked up" or doing the "pick up" ... one doesn't know the hygiene of the other party. They may be sparkly clean on the outside, but I doubt anyone takes the time to do internal cleaning when going out for the night on the town, etc.
Look, I apologize if I'm tossing ice water on the topic, I am just familiar with germs, viruses, etc and hepatitis is not a desirable experience.
I'll quit ruining the discussion ... I just try to be a practical & sensible person is all.
