I am very good at holding in my piss I once held in my piss for 3 days at my friends house bc I was too scared to use the bathroom bc it was too confusing and I had a big fear of bathrooms and people watching me
@tommcat4283 yea if ur bladder is overfilled it could effect ur kidneys really bad I'm pretty sure dats how u get kidney stones so if u don't pee for a long while a doctor has to extract ur pee out for u with a catheter
