well the cause for it is the body temperature. the food you eat and if you smoke or chew tobacco this may happen. when i say body temperature i mean your testis are at 2 degree C cooler then your body. but when you mastubate its temp increases due to friction on penis.
the best way to get quick relief is when you feel like peeing before peeing have a 1/4 glass cold milk and 1/2 glass cold water mixed together and drink it. then spend some time at the toilet seat. pee if you can. 10 to 15 min youll be better.
