I find it disgusting how many men do not wash their hands after shaking said dick.
The public urinals do not provide any tissue nearby for this kind of thing, there are some in the stalls but walking around with your dick out isn't exactly good manners.
I have a quick shake and then a dab with tissue. The whole "if you shake it more than twice, you're playing with it" quote is BS when it's not humanly possible to get it all off with just two shakes
