I thought that when Doc Mengele does the folded-out anus special, the tissues touching inside would be something like the inside of the intestine/anus, not healing themselves shut, requiring you to impale yourself twice a day for the rest of your life. Trannies are amazing in all the worst ways.
For Troons and Women with
hysterectomies vaginectomies who have a surgeon give them a fuckable surgical wound, there are two places the healing happen.
The first, which isn't a huge problem unless you want to be fucked in your man-made hole is your body will start building connective tissue around the colon-lined skintube and the skin used to build it will start contracting. This is user-reversible in nearly every case (with a lot of care), the closest example I can think of is retards who got their ears gauged and then stopped being quite as retarded and removed the guages - if you become a retard again you can start stretching the holes back out. (not a perfect example as the lobes will usually heal all the way closed)
The very bad thing that can happen here is if you try to go from zero to getting a train run with this, the skin tube goes into your abdominal cavity and unlike an actual uterus there aren't multiple layers of tissues. So there is a possibility of the skingraft fucksleeve turning into an internal abdominal wound. But if you are done having it used as a living fleshlight, there's no need to keep going for depth.
The second, which CAN be a very big problem is the opening healing shut. Since as manmade mockery of nature there isn't the actual cellular structure to tell your body "Yo, no, don't heal this one" that opening will keep trying to heal closed and you must make pains to stop that from happening. If you are done with that, you need to have a surgeon actually remove your fuckable internal flesh sleeve.
I was watching a video on a (natal woman, hysterectomy) who I guess she and her husband decided they were done with her fauxgina
(I don't know if they doing mouth&buttstuff, he was just hiring hookers, or just gave up on sex or w/e; it wasn't addressed other than that neither her nor her husband particularly enjoyed using her pocket pussy; her because it didn't feel right, him because there weren't any muscles, it was just a skin sac) and they just decided to let nature heal. About a year after she had to be rushed to the ER because she had a huge infection because her fauxgina didn't heal away. It just healed into a cyst that kept leaking assjuice (from the implanted surgical lining) and shed skincells and oils (from the skin they'd used) so she had a massive lump inside her that eventually some of the bacteria that had been sealed inside when it closed started rapidly multipling. So she had to have emergency surgery to get her fauxgina, now a pus and mucus filled flesh balloon, removed before it burst and covered her abdominal organ cavity with infected discharge.
Basically either the pussy maker didn't warn her (or more likely she forgot/didn't pay attention) but a troon hole, especially a colon-lined one, can't just be ignored when they're done playing pretty pretty princess. They need to have it removed.
tl;dr You may think you are disgusted by trannies, but you aren't disgusted enough.
