So I made myself a medicine-spoon STP and it's working truly admirably. But (obviously) it doesn't look at all like the 'real thing.' Having never successfully used a urinal (I have tried without a device when I had a men's room to myself while cleaning it, but that didn't work out) I don't know what it's like to stand at one next to another guy.
Now, I understand that the etiquette is to never stand next to another guy if you can help it. And of course looking is absolutely positively verboten. But sometimes places are crowded, and the urinal dividers are sort of short, and a lot of guys are significantly taller than me, and I have this suspicion that an obviously-clear-plastic dick would be something that someone might accidentally catch out of the corner of their eye even if they weren't "looking."
So, has anyone been outed while using an STP device at a urinal? Do any of the taller guys have some insight as to whether something like that might be noticeable? Should I just STP in stalls until I can get a passing STP packer?
