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.
- 13 days
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.

Nawww I totally meant what I said. Unfortunately for those that disagree who cannot read English, I explained a basic function with plenty of ‘ifs’ involved, so… good luck proving me wrong!!
- AbouBenAdhem@lemmy.worldEnglish13 days
Because of the inverse relationship between velocity and diameter.
- 13 days
Damn 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!
- 13 days
I’ve definitely seen public bathrooms where the previous occupant may have been utilising this technique
- tankfox@bookwyr.meEnglish13 days
Laminar flow means exceptionally smooth and directional without any turbulence or spray, so this would make sense if you visited a bathroom that was spotlessly clean
- 13 days
Doesn’t matter how smooth the piss flows, when it’s coming out the torso it ain’t hitting the toilet

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.
- 13 days
Don’t let me stop you from having perfect piss aim by performing keyhole surgery on your abdomen
- 13 days
In theory, maybe. Yet in the real world, enough foreskin to interfere with the flow makes for a smoother flow with no spraying.
- 13 days
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.
- tankfox@bookwyr.meEnglish13 days
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!
- psx_crab@lemmy.zipEnglish13 days
Likely slower due to the friction the fluid have to go through the length of the barrel. The benefit however is the accuracy it has and lower in decibel, as it act as an aiming device and a suppresor.
Your penis makes noise when you pee? The only noise I’ve ever heard is when the urine hits water/leaves/grass…
- 13 days
It sounds like a lawn mower in a kiddie pool full of spaghetti. Yours is silent?
- 13 days
A kiddie pool full of spaghetti is one place I haven’t yet tried peeing
Should I wait for the kids to get out?
Mine sounds more like me looking at how hot it is outside and thinking maybe later. Mostly quite, but a potential groan everyonce in a while.
13 daysNot a urologist, but I’ve got a bladder issue that has given me insight on this topic that I’ve discussed with several urologists.
In short: yes, penis havers piss slightly faster than non-penis havers. But only on average.
All sexes have a urethra, the tube in which pee comes out of, penises just contain a few extra centimeters of urethra on average, compared to non-penis havers.
These extra centimeters, on average, allow the piss to naturally “cycle” around the urethra a bit more, leading to a naturally higher velocity on exit.
To answer your question, there is a device that measures the flow rate of a stream of urine. This device is placed into a toilet, looks like a portable fan, and is pee’d on to determine the strength and speed of your flow over time.
It’s used by urologists to determine if you’re peeing good or bad, but 100% generates accurate information on the velocity / speed of your piss.
Not intentionally, but I did very well on one of these tests, literally pissing “off the charts” which lead to several conversations with my urologist on who the best pissers out there are. (Horses, Swimmers, Etc). Eventually confirming that men do (on average) pee faster.
- 13 days
So what you’re saying is that penis-havers have a rifled urethra, which contributes to higher muzzle velocity and accuracy, as well as the spiral shape of the stream?
- 13 days
Non penis havers
Can we PLEASE just start calling it men and wonen again? Yes, we all know what people mean, no, it’s not meant to exclude, yes, trans men with a penis can for this just be considered men (wouldn’t they want that anyway?), its all fine, and yes, this is really REALLY over complicating simple things.
It feels like people are walking on egg shells with words because dear god what if you accidentally misgender someone or use a word that makes 2 people in the world feel excluded? Peepee? Men. No peepee? Women. Simple.
- 13 days
Honestly penis haver gave me zero friction, what’s the issue exactly?
Like it just covers all cases and is explicitly about the subject at hand. Men and women is vague, full of exceptions.
- 13 days
My thoughts exactly, what about men that had to have their penis removed. Penis cancer is rare but a thing.
- 10 days
Please get some real problems to care about. Couple questions:
- How does this phrasing affect you in any way?
- How is you bitching about this less eggshell walking than other people bitching about non gendered language? Now people have to take your preferences into consideration. Or you could grow up, read the perfectly legible sentence, and move on.

I’m going to just say this. I hear my wife pee sometimes and it sounds like a water faucet. She has me beat at least.
- 13 days
Same here. she also finishes way faster, so assuming equally sized bladders it would follow that her flow is much stronger.
- 13 days
Time to harass my wife and compare speeds based on the sound of our pee streams. ✌️
- 13 days
Caution advised, I have just received a theory from one of your scholarly peers that a phallus may act as a scilencer thus making your method ineffectual. Perhaps pee upwards at a 45 degree angle and then measure the height of each stream to derive velocity?

Now I’m sitting here wishing I had rifling in my barrel so the pee would come out spiraling like those nozzles on some power washers.
- FishFace@piefed.socialEnglish13 days
but the individual particles in the stream are going to follow a ballistic, not spiralling trajectory. I think the spiral nozzles have to rotate; they can’t just be rifled.
- Rappe@sopuli.xyzEnglish12 days
I think they have a ball bearing on a groove, so the water pressure rolls it around in a spiral.
- 13 days
A long time ago I read somewhere that the human penis is indeed rifled.
- village604@adultswim.fanEnglish13 days
It’s wrong. The stream twists because of the shape of the urethral opening.
- village604@adultswim.fanEnglish13 days
No, rifling is spiraling internal grooves. The urine stream twist happens because of the opening shape and water’s surface tension.

I thought most mammals had basically the same time (where diameter scales with bladder size) from a full bladder. I’m not sure if I’m misremembering that.
- 13 days
You’re so right! At least as long as you aren’t so small that surface tension forms droplets
It works for shitting, not sure if the same applies here but it’s possible
defecation duration is constant across many animal species – around 12 seconds (plus or minus 7 seconds) – even though the volume varies greatly
https://www.scientificamerican.com/article/the-physics-of-poop/
Of course there are other factors (how full and how big the baldder is etc.) but I do wonder if the diameter of the pipe is smaller in a penis, and maybe less stretchy/flexible, compared to vulva urethra.
- 13 days
I knew a guy who had prostate cancer. They had to take his penis off. It’s quite shit of you to insinuate that he’s not a man anymore.
