A guy in Iran gets his penis tattooed with “borow be salaamat” (good luck on your journeys), and his girlfriend’s initials. Unfortunately, he went to a “traditional” tattoo artist, whose method caused the guy to get a permanent boner.
The tattooist punctured too-deep holes that damaged vessels in the penis, resulting in fistulas, and then a pseudoaneurysm, a pooling of blood outside a vessel wall. They recommended he see a specialist to have the blood removed, but he rejected that idea and saw another doctor to have a shunt procedure performed. It didn’t work. (source)
He seems pleased with the outcome, so he is rejecting treatment. Iranian doctors were quoted as saying “based on our unique case, we discourage penile tattooing.”
