Bit TMI but it involves bathroom related things.
I am one of the few guys who wipes their dick down after a piss, why? Because I do not want to deal with dribbles. That and I don't like having that tingly feeling in the front of my crotch after I'm done, it tells me that I'm making a wetspot at the tip of my dick and on the inside of my pants/shorts. I can't stand that shit, so I wipe down until nothing more is coming out. It is gross to me to see guys just do their business and zip back up like nothing. They must enjoy the scent of their piss or something.
And when your dick decides to spray than stream? Gross, because piss can get everywhere and sometimes on your legs which is even nastier and wastes more time in the bathroom. At work, I witness it all the time, some faggot sprays all over the seat and doesn't have the god damn courtesy to take a paper towel, douse it in foam soap and water and clean that. I'm not sitting in your ejected dead cells all over the seat, you disgusting animal, fuck you. People like that should be put down, they're incapable of pissing in the bowl.
