This is a good place to talk about the benefits of peeing in the sink. You run some water, splash it around to get any tiny splatters that may have happened (a good chance there weren't any), and then wash your hands.
So you're "flushing" it down the drain with soap, which is cleaner than a toilet would be, and you use a fraction of the water. You also get the added benefit of getting to watch yourself pee in the mirror so you can laugh at how small your dick is like everyone else does who sees it.
