    The velocity is proportional to bladder pressure and inversely proportional to the square of the diameter of the urethra. The shape of the body parts outside the urethra is irrelevant.

      This isn’t true because I can squeeze the tip of my foreskin and the pee will start spraying everywhere super fast. Similar to covering the end of a hose with my thumb.

        Similar to the hose, your feeble attempts at restriction only make the stream stronger.

        There is a fundamental pressure being restricted. IF she has a bigger urethra than you, she’ll wreck you. If she has a narrow urethra, she might be in the same support group as Hank Hill.

        Either way, the fundamental limit of how much pee can flow will always follow a basic function.

          I used to think that women had larger urethras than men because female catheters are larger. A post similar to this one caused me to do a bit of reading though. Women’s urethras are actually a little smaller on average. They can use larger stiffer catheters because their urethras are much shorter and almost straight. Men’s catheters have to be narrower because they have to be flexible to go through men’s longer curvier urethras.

          I don’t even think you know what you’re talking about let alone what I’m talking about.

          Damn, that’s crazy. Do you think the shape of someone’s genitalia has an effect on that velocity and diameter?

            The optimal genitalia for urination has zero length. Imagine a frictionless laminar flow from a razor edged hole in your torso!

              I’ve definitely seen public bathrooms where the previous occupant may have been utilising this technique

                You are doing a great job at showing everyone you have no idea what you’re talking about. What you replied to says there wouldn’t be any splatter etc.

                This post very single reply you’ve made here has only ticked more boxes on the list of showing your idiocy, ignorance and inability to understand basic concepts.

                  Doesn’t matter how smooth the piss flows, when it’s coming out the torso it ain’t hitting the toilet

              In theory, maybe. Yet in the real world, enough foreskin to interfere with the flow makes for a smoother flow with no spraying.

        Yes, partially covering the opening will increase flow speed, but it doesn’t matter how long the hose was before you covered it, so no penis is required to achieve that.

        You should try a twist tie, wrench it shut like it’s bread you want to actually keep fresh instead of just twisting it up and tucking it under the loaf like most men do. See what happens!
