Why doesn’t it hurt to pee?
I’ve heard that when someone gets something done (medically) to their urethra, it hurts really bad. What I mean by that is when doctors have to put a camera up the urethra. If that’s the case, then how does peeing not hurt like hell, I mean, there’s fluid coming out really fast and there’s pressure there so? It might be a simple answer but I’m pretty dumb and have been wondering this for a while.
Edit: Yes I’m aware that this was a dumb question. As I mentioned to one guy who commented, I didn’t think this question through thoroughly as I got back from work before posting this and was exhausted (I still am honestly). If you don’t have an answer or anything nice to say, don’t say it, kindergarten shit people. Thank you.

Thin fluid (urine) can get through small spaces much easier than a solid catheter/camera/etc can. Drinking water is easy, but swallowing ice cubes is not and can hurt your throat because it’s constricting around something rigid.
It hurts to pee when you have an irritation in your urethra. I have experienced these sources of pain when peeing:
* Urinary tract infection (UTI)
* Post-op after kidney stone removal (the catheter or endoscope inserted up the urethra leaves a bruise inside that hurts for a few days, and the pain is intense the first day)
* Passing a kidney stone fragment (feels like a UTI, hurts for about half a day)
Another pee-pain: The first knuckle of my left thumb hurts when I pee. This sensation developed about 10 years ago. I thought it was weird, then actually found a forum discussion involving people with the same problem, saying “yeah my doctor has no clue what’s going on.” I told my doctor and he said “you got me, I have no clue either!”
If the urethra gets stretched out enough that there are micro-tears inside (this is pretty easy to do, it is *very* delicate!), then yes, it’s gonna burn when you pee; there is salt in your urine and it aggravates your pain receptors, and the pressure of the urine will slightly expand the urethra, opening those micro-tears to the salt in your pee.
Because urine is liquid so it just flows, whenever there’s a medical procedure it implies something solid poking the most sensitive part of your body. Drinking water is easy, shoving a tube down your throat nos so much, same principle
In life different people ponder different things in different ways. OP is one of those different people.
I’ve had a camera up my dick, a cystoscopy. The camera isn’t a GoPro, it’s smaller than a pencil and you’d be surprised what they can fit in your dick hole. It’s not very painful and afterwards there is not much pain… Probably similar to getting soap in your dick hole. Just a little discomfort, which is gone fairly quickly.
I was scared to death but in the end it was really nothing to sweat and they got to see all the way to my ureters, and I’m not dying.
That’s my experience.
When you pee the urine thats touching your urethra doesn’t move that fast. If you ever note the most uncomfortable moment of peeing is when you start. After that things feel like no big deal.
What happens is that the molecules of urine that touch your body may have high friction. Those molecules though just stop. The main flow of the urine tochex those stopped molecules that create a cushion. All the rubbing happens between the urine molecules, and not your body.
When a sold object is inserted, they use some lubricant, but its not perfect. A liquid will always deform and separate as needed to not rub too much against the walls of the container. A solid object will rub directly causing a lot of discomfort.
the bladder is more of an exit only type of organ. Meaning it’s built to have stuff come out of it .and not built to really have things put in. cameras are going the wrong way. and a camera is a solid object while pee is a liquid
When you pee, you’re actually relaxing the muscle that holds your pee in (so to speak) so it’s able to flow freely without resistance.
Like you’re five? Solids scrape, liquid flows, and at reasonable speeds doesn’t hurt.
Like you’re >5: the liquid doesn’t all push through along the sides it probably expands the vessel with pressure and the flow isn’t really touching the wall. Think of blowing up a balloon animal balloon, the long thin ones.
