    No. The sphincter’s job is to prevent seepage in both directions.

    Doesn’t mean it can’t happen, but it typically does not.

    Why did you spell “climax” like that?

    I don’t know how it works for most folks, but as soon as my butt is fully immersed water starts shooting out of my ears just like those peeing angel statues, so yes, there’s necessary seepage. That’s why I just take showers.

        Well, I figured out within a day or two that face down ass up was not the optimal showering experience. It’s a steep learning curve, I guess…

    This might sound weird but this is an honest to god scientific diy test.

    Go to your shower, switch the head to high pressure mode, spread your cheeks and see what happens.

    The short answer is that the sphincter (asshole closing muscle) is really good at it’s job, which makes sense when you consider that even pretty loose poop can be held back for hours while gravity does it’s best to pull it out. So your sphincter is pretty strong and can handle some significant pressure, much more than your lips, so if you can keep the water from entering your mouth, your butt is fine.

      I had a disagreement once about whether or not “between the cheeks” counts as “inside.” The final verdict was it depends on the context.

        The crack is external, although I do wonder what different skin its made of. Like your lips

        Also tell us more, @meatbridge

          The inside rosy part is called the epithelium, for anyone wondering and wants to look it up. “Epithelium vs epidermis” gives a rough idea with plenty of diagrams.

    How immersed?

    Tye sphincter can and will resist pressure, but only so much. You won’t run into that kind of pressure freediving, or even anywhere you could use a wet suit afaik, but you get deep enough and it would become an issue.

    Or, if you’re immersed somewhere with water moving heavily, you could get breaches in your breeches I suppose.

      Really? Since your whole body is submerged there’s little to no difference in pressure. Our body is not a hardshell.

    I’ve been over 100 ft under water. The water pressure is at about 45 PSI at that depth. I don’t come up to the surface squirting poo water. There are people who have went deeper than that and never heard of it happening.
