Use the urinal.

"Ok, I got this", Vincent thought. Nobody else in the bathroom, so he went to the urinals. Vincent examined the urinal. He still had no idea why men pulled out their penis in front of others and peed into those things. The last time he had used one, he was around 12 years old and his pee had sprayed uncontrolled into any direction.

Vincent breathed in and unzipped his pants. He took his soft penis, around 2.5cm, between his thumb and his forefinger. He was still so nervous. He closed his eyes and tried to relax. After one full minute, he finally manager to release and let his pee out. It instantly sprayed around the whole area, without any control. Frightened, Vincent instantly pressed his dick together so nothing came out. He sighed. Then he slowly removed a bit of the pressure and pulled his foreskin back a bit, and an extremely small flow came out, not really a beam but more like a sequence of single drops falling down, one after each other. Finally he had found a way to control it, although it took an eternity. He sighed confidently and closed his eyes, all the stress falling off.

Vincent opened his eyes. All of a sudden, next to him stood a short black guy, using the other urinal, grinning at Vincent. He was so shocked, Vincent pulled his hand away, releasing all the piss at once, spraying onto the urinal uncontrollably. Before he could react, his blister was finally empty, leaving him in a bit wet pants with his drippy little dick exposed. He stared at the guy next to him in disbelief. It was Jude, a shorter black guy he had often mocked about being short in front of everyone, leaving him back embarrassed. Jude just stared down at Vincent's little wet dick, grinning. Vincent looked down and saw a big long black cock hanging dowm into the urinal. He just stared at Jude with an open mouth. Jude laughed.

"Now who's the small guy here?", he smiled. Vincent shaked his dick quickly, trying to get it dry. He looked down, totally embarrassed, trying to get away as quick as possible. "I've asked you something", Jude insisted, and Vincent could hear the pure joy in his voice. "I am, Jude", he whispered. "Are you happy now? Are you satisfied?" Jude pulled his pants up and laughed. "Do you even know what pain this is, everybody laughing at how short you are?" And he quickly turned around, looking deep into Vincent's eyes, all of a sudden furiously. "I will teach you", he fizzled. And he rammed his fist into Vincent's genitals, once, twice, three times. Vincent coughed. He had never felt this pain before, it took the air away from him. He coughed, he fell over. Vincent's fave turned red, almost purple, he couldn't move anymore, paralized from the pain, he lied down un his own piss, shaking. And Jude just laughed and walked away. After some minutes, someone found Vincent there, still with open pants, and he was taken care of by an ambulance, while everybody watched him being treated, with his little dick out.

From that day on, Vincent was unable to procreate, and his diagnosis was an open secret. A terrible time began.
