Well man, good luck first off. Secondly, they monitor the temp of the urine when it comes out. So if you are using someone elses be sure to keep it as warm as possible. So yeah, somewhere in the ball region is your best bet. One thing I did was to use a cover up product. It was called Strip but you need some time for it to take affect. Keep it warm and best of luck. They will probably have the blue toilet water and won't let you flush so carry out what you carry in. Again, best of luck.
