Cause like breast feeding is a baby eating, and it’s not unacceptable to eat in a lot of public places, as long as you don’t make a mess.

Peeing A: Leaves a mess, a mess that will eventually start to smell gross. B: Is something we have special rooms for nearly everywhere because it is considered a private act C: Also like you know who gets to pee in public, babies and anyone else who needs diapers cause they’re not squirting a mess everywhere.  The breast milk equivalent to whipping out your dick and peeing on a wall would be whipping out a boob and squirting breast milk everywhere to relieve boob pressure

Also like there are societies where everyone walks around in the nud all the time and breast feeding is no big and you still don’t just pee wherever..
