Open and Shut Case

So here's a question just for the men. What's the proper protocol when you are forced to pee in the stall toilet rather than the urinal? I've never felt truly comfortable when faced with this dilemma, though it happens rather frequently. You walk into the men's bathroom, and there are a couple of occupied urinals and an open stall. Lurking behind the guys at the urinal feels a bit awkward, so you head for the open stall. But what's the next move? Do you close the door or leave it open? Closing it gives the appearance of a guy scared to pee in public. Leaving it open, though, gives off the creeper vibe of one who is inviting your fellow man to take an unnecessary gaze at your pee session.

I always end up devoting far too long to the situation and trying to appear casual while easing the door to the near closed position. Inevitably the door will slowly open as I pee, leading to thirty seconds of profuse sweating and panic.
