An affliction of males characterized by unusual behaviours in the men's room. Urinal anxiety is manifest in the actions of a man who walks into the men's room and heads directly toward the urinals, but -upon seeing another man already standing at a nearby urinal- immediately changes course for the stalls. Urinal anxiety afflicts a substantial number of males who have a phobia about pissing in a location where another male might notice their schlong (as if other males would have an interest in someone else's schlong...). The most extreme form of urinal anxiety is usually seen in locations using the old "trough" urinals often placed in ball park restrooms. The afflicted male approaches the other happy, piss-spattering companions, pulls his dick out, and... and... and... (after a long delay) zips his dick back up, unable to urinate, and shame-facedly departs the restroom unsatisfied.

I have this condition and I'm not male... but what this is is basically not being able to piss when someones right outside the bathroom or is in the bathroom stall next to you for fear of someone hearing you pee or accidently blasting one.
