Sometimes if I’m overly full the bladder gets overstretched and I can’t fully empty in one try.  It’s like the muscles that contract to push the pee out can’t contract as much because of the stretching.  Thus the flow is slower and I can’t fully empty until I wait a few minutes.  Then it “unstretches” some and it can squeeze the rest out.  It’s like a latex balloon after you inflate and keep it full a while, then let the air out, it is stretched out and has less pressure. From what I read here I guess it happens to men more than women.  But I think it depends on the individual and how strong their flow is normally.

Welcome, You'll love this sight. I love peeing on bathroom floors, and hotel carpets as well, it's so much fun!!!

It's impossible for me to have a slow flow when i'm very full, due to my much smaller than normal bladder. If i go beyond the maximum capacity, the pressure is very strong.

Yes, when I hold until painful and my bladder feels like a rock is when it happens to me.

There are multiple ways for a woman to do so. 😉  https://pisshamster.com/86175-pissing-in-the-sand-brazil-beach/ https://www.xpee.com/video/15672/peeing-while-trying-to-get-the-perfect-tan
