How do you hold your pee in class?

Answer 1

If you are in class, raise your hand until you are called upon to ask politely if you can be excused to go to the restroom. When your teacher says yes, go to the nearest restroom. In college classes, however, most professors prefer that you quietly get up and excuse yourself without disturbing the rest of the class, and again quickly and quietly return to your seat when you return. If you are in between classes, just walk to the nearest restroom and use it.

Answer 2

Think of the dry dessert; don't think of water or cold. Just think of how dry (don't think "not wet" don't think of anything pertaining to wetness or water) it is in the dessert. Alternatively, pay attention to the lesson and you would hardly remember you wanted to use the toilet.
