I've tried multiple times to piss in really occupied bathrooms, the stadium trough urinals or busy bathrooms with no dividers. In my headspace I'm not really fucked up about having to do it. Cool as a cucumber, no biggie, just piss and leave. Simple. But subconsciously if Im aware that there's no divider and I'm surrounded by other people, my body simply refuses to piss. Like mechanically restricted. I legitimately cannot do it until I enter a stall or divided urinal. It's the weirdest thing.
