I'm sure the record will be quickly cleared up but there is a version of amhole surgeries using a portion of the colon as the interior lining (iirc). Those ones are the ones that constantly complain about their new fuckhole constantly smelling like shit, to the point of even making whole rooms smell like shit. While I also agree with you, because they are nasty fucks, some do come with their own built in fecal bacteria afaik.
It’s pretty impossible to get rid of your colonic bacterial profile- without nigh on dying.
as a baby born the standard way, you will pick up the same fart smell/bacterial profile into your bowel, via your umbilical cord contacting your ma’s poop- the fact is that when your mother gives birth, there’s a lot of splitting, occasional shitting of self, a whole lot of spread bacteria going around.
And you keep that for the rest of your life- unless something really bad happens to your guts and you need a fecal transplant or something. To get that bacteria back up to scratch- like if you have Dysentery you can shit away basically everything and with an empty gut you’re in trouble trying to digest things properly- it’s why colonic irrigations are still a privately bought thing and not really a regular medical practice.
It’s kinda bad to be washing yourself out like that.
For more gross birth shit:
Now, if you are born by Caesarean section, they get a cloth, wipe it in your ma’s vag, and wipe that all over your newborn face.
All the bacteria is badly needed- kids born by C-section and kept sterile tend to end up with asthma, allergies.. all the lame little dweeb kinda thing.
All this to say… fecal bacteria sticks around, and even if you’re not using a section of colon to make the neovag, stabbing around in that area of going to introduce it the bacteria, and it’s gonna stick around in there and set up camp seeing as there not much else going on in the cavern of misery:
The body (and nature generally) does always try to build little dynasties to make sense of … man made horrors beyond our comprehension- nature gives its best go at making a shot of it though.
