Yes, of course. It's one of the first things to do on every exhibitionist's to do list. I've done it and finished while no one was there. I've kept going a couple times even when someone showed up and with no dividers. They usually walk away before I finish.
The trick is to do so casually and somewhat discreetly making it somewhat indistinguishable (just a couple fingers or use fingertips, not the whole fist thrusting & pumping away getting your whole body into it, unless they obviously want you to). That way, they'll only notice if their interested and want to look and see it anyway, (which someone interested would never snitch on someone who probably just made their day), or, you've been "pissing" at the urinal for more than 5 minutes already.
I've even started in an empty bathroom and had someone show up just in time to catch the money shot, and one guy did also call me a pervert! Wow, mission accomplished! My question is, if I'm the only pervert in the situation, how is it that you witnessed my ropes of cum shooting out of my cock if you weren't already looking as you walked up? Cause it's not like I had my body turned to face the doorway or was standing further away from the urinal than most guys do.
(Also, I can't tell you how often I'd end up alone working my pipe, while driving, on the side of the road, in parking lots, at urinals, in public playing pocket pool in my pants or front hoodie pocket inevitably pulling out to finish, just to have a random guy show up and look over just in time to catch the money shot. It's almost like fate ALSO wants them to see me blow my load! I've only ever had one complaint and that was the one time a guy whispered the word "pervert" to me with a frown, who probably had some repressed bicuriousity... Gotta play it smart out there guys, or just be on the move. Cant go to jail if they cant identify and/or find you
