ELI5: Prolapse porn - aren't these performers seriously damaging themselves?

While I understand that niche porn is more widely available and in demand now, and the pay rates for the more extreme acts are very high.. This isn't safe for them, is it? 

One would assume that if a performer had a prolapse, they wouldn't want to irritate it any further despite the pay for the sake of their health - or is it, in fact, not that extreme a condition?

I'm not here to kink shame, I'm genuinely curious.

Depending on the type of prolapse and how it's done, the performer can, in theory, push the prolapse back in by him(her)self. The images that look like it's just a small portion of tissue hanging out can and probably just shove it back inside.

A prolapse is akin to pulling a sock off your foot and it turns inside out; your rectum pushes out your anus. Now, the simplest form is just a bit of the rectum lining coming out and the worst is the entire rectum plus getting the large colon involved.

Depending on how often the actor prolapses, they could in theory, strain hard as if they are having a bowel movement and force out the slimy bits, or another cause could be a penis or dildo being forcibly pulled out of the anus when the receiver is unprepared and the rectal muscles/tissue are already weakened by poor pelvic muscles and a rectum that has already prolapsed several times.

If done "correctly", the performer would constantly be bearing down, keeping their anus from closing around the tissue and cutting off the blood supply, which could be deadly under the correct circumstances. Once done, they just lube up the offending rectum and gently push it back inside. As long as they aren't forced to prolapse on a regular basis, in theory, it could be a "safe" kink, but will most likely require surgery after their career is over to keep their bits from falling out every time the pee, take a shit, vigorous sex, or even by coughing.
