The Men's Room

So, it's late at night at the office and on my way to the ladies' room, I passed the men's room. The cleaning people had propped the door open and my co-worker was using the urinal. The embarassing parts were blocked but it was still very shocking. I'm wondering if guys have seen each other's goods?

Update: I have asked 2 guys at the office and they have never "seen anyone's junk."
