Why do you have to go to the bathroom?

You have to go to the bathroom because it flushes out your system so if you didn't go to the bathroom you would be likely to get an infection where you would have to go to the bathroom 24/7 and if you don't go to the bathroom its going to be pushing down on your bladder and that's another way to get an infection!. also you might explode jk you know nevermind...
