I have this problem, but I'm a girl. I avoid public bathrooms like the plague, and even in my own house, I can't go if there's someone nearby. If I was a guy and had to use a urinal in front of three other dudes... nope. xD
The art is a little rough like the others said, but it was a cool style. Wish it had been coloured and shaded though, but you're a good storyteller. xD
