why is that some men fart when they pee?

Only "some" men?  lol!\n\nThe urinary and rectal sphincters contract and relax in unison because the same nerves control both sphincters.  When the urinary sphincter is relaxed to permit the flow of urine from the bladder, the rectal sphincter similarly relaxes.  Add to this the fact that men often bear down or 'push' during urination in order to more completely drain the bladder and it has the effect of pushing gas out the rear exhaust port.

women's urethras are shorter than that of males. when a man has to urinate he can actually delay the enevitable for a while through a natural response in his body. when a man gets an erection it actually pinches off the opening of the bladder until his erection goes away. which is one reason men get night erections (the other reason is that we think of sex all the time...even when we sleep)

Because pooing and farting require the same basic bowel movement and runny poo can be quite sneaky!!\n\nTGW

cough so they won't mistakenly open your stall door, then let er rip. \n\nonce i was at the denver international airport and i was taking a piss, and some dude was taking a noisy a$$ sh*t.  all the sudden he expelled the loudest piece of crap imaginable, it splashed loud and everything.  then some dude peeing in the urinal next to me yells, "ALL RIGHT!!!" super loud.  that's how taking a crap in a public place should be - like a sporting event.

For the guy or the girl? \n\nMen typically have to urinate after sex to clear the urethra of seminal fluid. \n\nWomen are advised to urinate after sex as they have an extremely short urethra and sex can actually force bacteria high into the urethra causing a bladder infection. This is just to flush away fluid and bacteria. \n\nAnd some just need to go pee...

same reason men masturbate

Because it closer to the begining of the digestive journey.   When a fart comes out - it has had to go through the intestines and it picks up all the stinks that are in there!!  The gases get more noxious if you have a stomache ache too - for some reason it just rots in there and really wreaks everyone out when you pass it.

well probably your fart just comes out and when you are doing your duty you push to hard that happened to me ONCE but just be careful i heard that that is bad, when you push to hard when doing your duty.

Funny...\n\nI think the smell you are describing is directly related to a fart..\n\nSeriously..\n\nWhen you eat different things, does it not make your Farts smell differently. \n\nThink. \nWhat does a beer fart smell like??\nHow about when you eat beans?\nWhat does it smell like when your Golden retriever eats beans??? Whoa...\n\nGarbage in, garbage out. \nIt either leaves out the anus or it leaves through your pee pee...\nIt takes with it what your body does not need.\n\nFor the record, Mine Urine smells wierd when I take an antibiotic.\nThat smell is much different than when I take a strong vitimin. \nDid ya notice it changes color too?\n\nI wonder, if small paricles of your urine are floating around in the air when you pee so that you can smell it, Are germs floating around so you can inhale them too?\n\nCould you get sick by smelling MY urine??\n\nWhy would you want to go around smelling urine?\n\nGADS, I think I will pee sitting down for now on and flush 4 times.

Germans are very into peeing on each other. It started as the healthful practice of preventing urinary tract infections by clearing the tract(peeing) immediately after sex, and eventually some people started incorporating it into the eroticism. No harm in it really, as urine is completely sterile.

Well, it depends...not all farts are stinky...some farts are just air...while other farts are deadly gases...but if the priest cuts 1 that is stinky then by all means the fart will be stinky...anyways, what does sitting in a pew have to do with it?  The only thing that comes to mind about farting and pews is that if you are sitting just right then that bad boy fart will reverberate on the pew and make the fart sound louder.

Its when theres an air pocket and we rub it and we push that air pocket...so it makes a farting noise.\n\nIt happened to my ex a few times long time ago, but I knew it was normal so it didnt phase me.\n\nAll men know its a normal thing, so dont wig out...its a beautiful thang.

interesting. i've always joked with my bf "if he would like a hand" while he pees but he usually laughs and says no. do you have to do it every time? then that's weird.

Ejaculating causes the prostate to contract thereby ejecting the semen.  The prostate surrounds the urethra (tube from the bladder out the penis) at the base of the bladder.  This is where the nerves that sense that the bladder is full reside.  Thereby ejaculation will often be followed by a need to urinate afterward.  This may have been a built in mechanism to prevent any sort of infection from starting up after intercourse.

Wouldn't air be a certain kind of gas?! Anyway, you are right, it's just air, not a fart.\n\nThe sound may be the same and it can be embarassing during or after sex, because the guy may think you just farted, but I think this is quite normal.

They smell, even, before they pop. You would have to intercept them to find this out. . . . and, indeed, they do smell even after they pop (or is it poop?). \n\nThe only thing the water does is cool them down a bit. The temperature of a fart at inception is 98.6 degrees and maybe let a little diffuse into the water (but not much).\n\nAn interesting little fact is that when you detect odors you are actually getting a tiny bit of whatever you are smelling in your nose (hmmm?).\n\nGotta let this go now.
