Haha damn, so classy

Yeah it is a possibility. I didn't mention it, but of course everyone expects hygiene in bed. Unfortunately, some people are not clean, but then it is a problem for every possible sex act, not just rimming and anal.
If someone is dirty, you can typically understand it even before they get undressed.
If the person is clean, then "accidents" can still happen. But if the hole is cleaned inside, then your finger will come out clean. It might happen that the tip of your dick is a bit dirty when you go very deep inside, and in that case the bottom gets embarrassed, you reassure him, change the condom, give another wash inside and then restart and have a laugh.
And as far as hemorrhoids and anal fissures are concerned, they are very unfortunate, but typically a person with a wound on his hole won't be looking for anal sex, right?
Would you be looking for a blowjob if you have a penile fracture or a painful urethritis?
