My trick for dealing with “blushing bladder” is a Palovian response on myself. I realized I had certain pee triggers. Long story short, there are certain places and situations that cause me to need to urinate. So I figured why not use a word as a trigger? While at home I began saying the trigger word just as I felt the flow begin. Every time I pee, I say the word. My blushing bladder went away. Some of the music venues i frequent have urinals literally elbow to elbow so it’s awkward but there’s no trouble when I say the trigger word. The only problem now is people look at me weird when I’m looking at my dick saying “shazam”.
Urinals should definitely exist because they speed things up a ton. If you’re too shy to piss into a urinal just go to the shitter instead. But don’t dare try to take the speed and convenience away from the rest of us, goddammit!
Do you think that you need to pull your pants all the way down and sit to use a toilet to pee, if not what are you doing in the stall that wastes a ton more time? It’s not much slower from my experience just do it the way you would a urinal, with the only difference being that you have a door and real walls.
The speed comes from space efficiency. Instead of one stall you can have three urinals (idk the conversion rate, but you get the point)
