So, I’ve been reading about the MIT bio suit. It’s basically a pressurized helmet and gloves, and a fancy fabric suit with bands that squeeze you with enough pressure so decompression doesn’t kill you.
However, since the body is not pressurized, would there be an immediate and constant flow out of your private bits the moment you stepped outside the space ship?
But the pressure from the atmosphere applies to both sides of the sphincter, resulting in zero net pressure. Unless the suit actually does press against the outside of the sphincter like it does the rest of the body, I think OP’s concern about the suit squeezing you like a tube of toothpaste is valid.
Maybe the suit only applies a few PSI instead of the full 14.7, which it seems like one’s sphincters would be able to withstand.

I think it’s like a third of an atmosphere or something. Enough to comfortably achieve the same partial pressure of oxygen as normal Earth air, by providing it pure.
