Depends on where your going. Some restrooms are down right NASTY. Usually the true question is, do you wash your hands BEFORE you go.

Think about it. Your hands are int he wide open all day before you go. Exposed to got only knows what. Your genitals are tucked nicely into your pants with boxers/underwear covering them. In reality, do you really want to expose your dick to your nasty ass hands.

Sometime's i wash them after, sometimes I dont.

Usually the sink handles are just as nasty as the urinal handles, so infact what does it really matter? I flush with my foot anyways, and rarely use my hands to steady myself.
