Your rectum has an internal and external sphincter. When the internal sphincter encounters pressure there’s a whole neural pathway that decides whether to let the external sphincter relax based on if it’s gas or solid.
Have you ever tried washing exercise clothes? The smell persists.
Farting is normal, and i assume that with the gas escaping, little poop aerosols come out too. Not something any doctor can help with. It’s just part of being human.

If you can smell a fart, you are smelling poop aerosols.

Not necessarily, gasses smell too.

I hadn’t considered this! So when you poop in the toilet, the bad smell is partially from gases, not entirely from airborne poop particles?
I’m also really sketched out about how belly button lint is from underwear, but i guess that’s off the topic.

The odor is from sulphide gases.

Sulfide gas smells different, more like rotten eggs.
Farts smell like poop.

My exercise clothes come out the wash as fresh as a daisy, and they have been through a lot and get washed at 30C.

Maybe that is a difference – i usually wash them as cold as possible to try to make them last longer.

It also makes a big difference if you wash them right away vs if you wait a day or two

Thank you for actual advice. It seems like at much of this thread is missing the point of No stupid questions.
