Why You Pee, When You Poop

We’re talking sphincters.

I know I am not alone here. At one point as a young boy, when my body was able to gain control of its bowels and my mind started to be able to critically think, I began to ask myself, ‘Why do I always pee, when I poop?’ Its something thats always wracked my brain but Ive always been too nervous, too afraid, to ask. Now fortunately enough I have people in my life I can reach out to for things when need be, but this, I’ve never known who to turn to. When you pack piss, shit, butts, wieners and science all into one question, however harmless it may be, it’s a lot to unpack. Ask your parents? Sure they wiped your ass for a good chunk of your life, but thats an awkward conversation you’re not willing to have. Your doctor? No way are you telling them the truth about anything. Your teacher? And risk embarrassment in front of the entire class? Not a chance. Theres just no one to turn on this topic so you continue to drop trow, pop a squat and wonder why you’re peeing even though you only felt as if you needed to cut rope.

Well folks, here is your answer. We have internal and external sphincters in both our anus and urethra and control the flow of pees and poops. The internal muscles are involuntary and urine and stool move through them when the muscles relax, alarming us that we have to relieve ourselves soon. On the flip side, the external sphincters are voluntary and we have control over them, to some extent. Now in comes, the pelvic floor muscles, the big answer to our question.

The main reason is that the muscles of the pelvic floor play a role in defecation and urination. The pelvic floor muscles relax when we defecate. However, they will not necessarily have to fully relax when we urinate. But when the pelvic floor musculature does relax, in addition to allowing stool to pass, it decreases the tension in our urinary sphincters, allowing urine to flow. Because our anal sphincters are stronger than our urinary sphincters, it is easier for us to have control over our bowels than our urine.

So when you simply have to pee you have the ability to hold that pee in as we all know. Some are better at it than others. When you are really are a really on the verge of going you can squeeze the tip of your dick and buy yourself some more time. Same goes for when you’re baking a loaf. You know you have to go at some point in the near future but you can clench those cheeks for the time being and deal with the barbarians at the gate in a bit.

The difference is that your bum muscles are way stronger. Can basically create a vacuum seal when you flex em. Turn a stone into a diamond. They can stay closed when you pee. The muscles you use to hold in pee just don’t have that core strength. They skip leg day. Don’t show up to OTAs. Sure they give you all they got right from kick off, but you see their weakness once you give them the first break and they don’t perform like they did in the first half. So when you decide its time to bust a grumpy and really relax those pelvic muscles, your pee hole has no choice but to open up, even if you didn’t feel the need to pee.

So next time you’re ready to download some software and you park yourself on the can, just remember, you have no say in whether you’re going to pee. Once the Browns run through the tunnel theres no choice but for the sprinklers to turn on. I don’t know if there are exercises in strengthening your pee hole muscles, my research ended when I got my answer about why my stream is simultaneous with my steam and that was all I was looking for.
