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.

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.
