How is shoulder-deep fisting biologically possible?

This question is to those of you who are into extreme porn. So I just saw a video of a guy fisting another guy all the way up to his shoulder on Twitter. He pulled it out in the end too, so he wasn't an amputee or anything. I searched the web and saw that this is actually a thing that people do. I just wanna know how that's biologically possible. Like, how do their intestines not tear? How does that even work?

P.S.: Sorry for ruining your day if you never knew about this and decided to Google it.

Help us keep this site organized and clean. Thanks!

    I honestly think fisting is disgusting. If they're not wrecking themselves now from doing it, they're going to do so in the long term. This is coming from someone with abnormal fetishes. XD

    I don't think there's no harm in it. It might not come at the very second they uh.. fist... but over time. But I've never tried it nor do I want to so idk for sure

    That's really fucked-up.
    Why would anyone even want to try that?
    I don't even want to Google it.

    I'm not a doctor and nor am I an expert on human anatomy, but I find it hard to see how someone could insert an entire arm in the large intestine without causing damage.

    My understanding is that while the small intestine is free to move around in the abdomen, the colon is normally attached to the abdominal wall and it should go up the left side to a point just above the lowest ribs, across the body and then down.

    There's a very good reason why the intestinal tract is protected inside our bodies. It's not a very robust structure, so it's entirely possible for rectal fisting to result in tears or stretching.

    The thing about extreme porn is that you rarely see the gory, painful, expensive and embarrassing real-world consequences of what people do for a few bucks or just their moment of internet fame.

    I'm cool with pretty much anything kinky unless it has implications for my life health wise.

    A prolapsed arsehole is one of those things that have health implications, so i'd avoid that if possible...
