Why Pee When Pooping?

Dear PoopReport,

I have a question: Why must you always urinate when you poop? What is the physiological reason? You certainly can urinate without pooping....

Just curious (I'm a nursing student).

-- Margret





Dr. Adams says:

This is an interesting question. There are many muscles (both voluntary and involuntary) that are involved in helping one to both urinate and pass stool. These muscles have dual functions -- holding urine and stool in, and passing urine and stool to the outside world. The muscles that help to hold in our stool are stronger and larger than the muscles that hold in our urine.

The primary muscles that function to hold in stool are the internal and external anal sphincters. The internal sphincter is a completely involuntary organ, and as stool passes through this sphincter, the muscle slowly relaxes. The stool then contacts the external sphincter, which is a completely voluntary organ. At this point, we sense that there is an increased pressure in our rectum, and we likely feel the need to defecate. If a toilet or other commode is close by, we sit down and voluntarily relax our external anal sphincter, and the stool passes through. If, however, we would rather not have a bowel movement at that moment, we voluntarily tighten our external anal sphincter, and the stool is retained in the rectum.

Control of urine is similar. The muscles are smaller, but the concept is the same. There is both an involuntary internal urethral sphincter and a voluntary external urethral sphincter. The internal urethral sphincter opens when pressures inside the urinary bladder are great enough; we can hold back the urine by tightening our external urethral sphincter, or we can urinate by relaxing this muscle.

So why do we often urinate when we defecate, but not vice versa? 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.

Of course, we all don't have normal control over our bowels or bladder. There are many conditions that can adversely affect our bowel or bladder continence. Also, the control of urine and stool differ in men and women because the anatomy of the male and female pelvis are so different.

But that can be covered in another "Ask Dr. Adams". Or ask Dr. Ruth.

And when you do sit down and process a bowl movement make sure your (dingaling, (sorry, didn't know any other way to explain it)) is pointed down and not even with the crack in the seat, otherwise it will end up on the floor on your feet. Unless you just want warm urnial leak on your feet or something weird like that.

Sometimes, though, you can't do one without the other. If you are standing at the urinal, you start peeing and have to stop because the turtle head starts poking.

This explains why women can hold in farts during vaginal exams.

EricPooped - good point. This did happen to me once when I was so tired I just sat on the bowl and sort leaned back. My doink was therefore approximately horizontal and it was messy. And because of the previously discussed muscle control (courtesy Dr. Adams), I couldn't stop my pee too well without stopping or interfering with my poo. In fact, it was all rather confusing at the time because I had just woke up so I just thought what the hell and let it all go.

On a side note, a friend of mine told me recently he is trying to stop his young son from peeing the bed, so he wakes him up at 3.AM every morning and makes him go pee (don't know if this is an accepted training technique, I don't have kids yet). Anyway, the son eventually got the hang of it and would get up to go pee. But one early morning he awoke with a boner and sat on the toilet, waiting to pee and so sleepy and disoriented he ended up hyper-peeing all over himself. I laughed at the time.

Hey, I like the feeling of warm pee on the back of my trousers after a good poop. On a related note, my co workers wonder why my chair always smells funny.

Poop feels good, but pee through the crack does not.

The technique Eric mentions of holding your dick down when you are on the pot is informally referred to as either 'tucking' or 'taking a tuck,' because you are tucking your dick in or down so as to avoid urinary disaster. Strictly a male concern, and I remember clearly being told by my father when I was a little guy, to hold my dick down when I was on the toilet. In addition, the practice also affords protection from contact with hairy porcelain rims.

If only my father had told me to hold my dick down while pooping. I ended up learning the hard way:(

I find I tend to do pee when I pass a motion. It is possible to have a totally dry motion, in theory at least, but I don't know of many people who do.

Is this why my morning piss is often coupled with a twenty one gun salute of sour, greasy farts?

But what about those times when you have eaten too much lasagna and the ricotta cheese has created a little monster inside you that you do eventually have to give birth to? Nothing better than that relaxing pee in the aftershock of giving birth to that baby! LOL!

Speaking of pee, I just read something sick about professional athletes in next week's TV Guide. It seems that some athletes are so pumped up that rather than take down their pants at half time and take a leak they stuff towels down their pants and pee into them. Aw, man that's sick!

I want some ideas for a girz pissing contest. Anybody?

The Shit Volcano's picture

Here's some ideas for a pissing contest:
1. Color. How yellow can you flow? Better yet, what kind of strange colors can you make it.
2. Length. How long can you piss?
3. Volume. How much can you piss out?
4. Most creative pissing device. Pee in a cup? Hell, no! Try something interesting, like using pee to generate power or peeing to open the refrigerator door. Just be creative!
5. Target shooting. Boys can do it. So can you. It's just... downward.
6. Name writing. Judge for speed and accuracy. Get those hips flying!
7. Best piss of the year. Who's the yellowist, biggest, longest, most creative pisser around. The winner will be determined here.
Oh, and be sure to have a pee fair on the side. You can sell all sorts of devices for making peeing more convenient. You know, those hiking shorts that open on the bottom, the SweetPee, a machine to extract drinkable water from pee (and other bodily fluids), theories on using pee to cure cancer. Make sure to have some piss-powered kiddie rides on the side and maybe a yellow pee fountain. (Or orange if it has a bladder infection!)
Bonus Exibit: Pussies that smell like fish. What, why, and where?

I, too have seen a white poo. It's usually poo that's been sitting there a while and so all the brown has run out of it. Dogs are good at making their poo turn white.

I actually don't piss when I shit. I piss a little before, and then piss a little after. This is how I know that I'm doing shitting. Interesting.

Here is one I really hate! when you piss in the bowl and you have to chop a quarter pounder logg off and the back splash is so great the piss splashes all over your ass hole causing a ph unbalance down there!

But can a man shit while he's coming? I always used to wonder and then one day I found out. It was an almost spiritual experience, similar to my first.

I've been talking pee with other people for a long time, and I learned something. Some people can seperately control their front and rear holding muscles and some can't. Oddly, each type is reluctant to believe in the other. I personally can't hold pee while pooping and vice versa. It feels like the same muscle holds onto both. I used to assume they were a single muscle until I talked to people who could actually hold their pee while pooping. They're on the same nerve for me though, every twitch of either holding muscle is felt in both places. I've spent a lot of time trying to operate them seperately, but there's no way. I wish I could.

I had an embarressing moment once in a pub, after a few beers I was bursting for a piss, so I went to the gents, stood at the urinal side by side between 2 other guys.. And then it happened, I shit myself, and it stunk bad, they both laughed at me before having to vacate quickly. I had to stand take my trousers and pants off and stand there washing them in the sink, got a few funny looks from people when i was standing there naked from the waist down.. My mate came to the toilet wondering where I was, and found me standing there with my cock and arse out washing my pants in the sink. I've never lived it down since.

I've never been able to hold my piss in while I drop trow, and I hope I will never be able to. It's so relieving when you've come from a nasty battle with a giant turd to have warm fluids flow from your body.

I have long wondered why I pee before I poop. Good answer!

But I notice that I know I'm "done" when I pee just a teeny bit more at the end. I've no explanation for that.

The difference between "poo" and "poop"...
one has a pee only at the beginning, the other has a pee both before and after!

How can you tell if your turds are tired? They get pooped out!!!

It is easier to keep your (this is my best description) winkie where it belongs, if you have an elongated toilet bowl.

Back to topic. "Why "must" you "always" urinate when you poop?" Key words here, must and always. There could be many reasons. 1. I personally don't urinate and poop at the same time, therefore, I would guess that it is just how the individual's body works. 2. Maybee some people's "urinary spinchter" is weaker than other's. 3. It could be psychologically related. There could be many other factors.
