Can anyone explain me this situation and i was left embarrassed as i got everything around me dirty. Why did i piss when the pressure was in a totally different hole?
Well you answered your question yourself, you might be holding your piss for a long time and when you felt the pressure in your other hole. The pressure made you break the other pressure that you were holding your piss with. In simple words Humans are not use to multitasking so when you divert your attention to one thing the other thing stops.
