But what if poo piles are literally coming out if it multiple times a day and being sprayed from it with every fart and anal pucker.

Sure, a pussy can be dirty. But if a pussy is dirty, guaranteed the ass is toxic. If a woman is going to clean either, it's going to be the pussy. A woman with a clean pussy still needs to do some prep before you go chowing on her ass.

Plus, the pussy has a self-cleaning mechanism. So even a woman with average hygiene (takes a shower occasionally) will have a pussy that's generally safe for consumption, notwithstanding any STDs.

The ass' only job is to jettison waste from your body. It's literally just a shute for poop. It doesn't clean itself because it doesn't need to. It's gross because that's its job. A lady will need to be asked to do extra work to clean that shit up for you. Which is fine in the bounds of a relationship with trust and communication...

But it seems a little unreasonable to expect that of a random encounter with Daphne or Velma.
