I notice when I masturbate (happens already during stimulation) my bladder gets full and I must pee whereas if I hadn't masturbated I'd get urge to pee later sometimes I'd edge get urge to pee and go and pee then after half hour edge and get urge to pee again and then another half hour later get again urge to pee although I may have drank more before but sometimes even if I had peed and hadn't drank that much touching activates the urge to pee.
