Of course, soap is still soap and it's our number one defense against more harmful forms of bacteria, like whatever you got on your hand after it ripped through that ghetto brand toilet paper public restrooms use that seems to be cobbled together from whispers and recycled Chinese newsprint. So it's kind of a "damned if you do, damned if you don't" situation.
So Keep That in Mind When...
...some guy gives you a dirty look if you fail to wash your hands after just peeing. Look, if you showered in the morning it's unlikely your dick is very contaminated. If anything you've probably made your clean dick a little dirtier by touching it with your filthy hands.
And both will wind up cleaner than that guy's hands who, after issuing his disapproval, touches one of the dirtiest surfaces ever invented by man: the handle on a bathroom faucet. Then he compounds the infestation when he touches the handle on the restroom door on his way out. Yet, if you so much as use your dick to open the door just one time, you're the bad guy.
