Anal itch (TMI)

When a person’s anus is less than 100% clean (say, due to seepage), what causes the itch? Is the skin sensitive to certain chemicals in the feces, and does this have to do with the food eaten? And in what respect is it different than the skin ***inside ***the anus, which presumably doesn’t itch?

Try dripping water down any part of your body, it feels weird and inspires itch.

The skin inside is a mucous membrane, which produces a protective layer of mucous. That is why your body doean’t digest itself, being mostly meat.

The anus is a sensitive area. Extra moisture or material there is easily sensed. I don’t know that it automatically itches unless the moisture has caused irritation. Cleaning and the application of Vaseline should be helpful.
