I'm in Texas, and a few bars definitely have the urinal and toilet with unlocked door combo, but everyone treats them like a single user bathroom. Before learning how to use a urinal i just let my shirt or jacket hang down and cover my crotch area while sitting down. I had a guy walk in on me once but by the time i finished saying "hey, ocupado!" He was already backing out the door with a "sorry buddy!"
Random Roads, if you have been on T for almost a year i imagine people don't look twice at you, i wouldn't be too concerned...
