uhh … for people with phimosis, there’s kind of a way to clean it (somewhat) regardlessly. basically, pinch the tip of the foreskin together while peeing. that will inflate the whole thing (foreskin) like a balloon while it fills with piss. then, release the piss. do this repeatedly and it will kind of be similar to a light rinse with water under the foreskin. piss is almost sterile so there’s no risk of infection from this. you can use your fingers for pinching, just wash them afterwards.
