New York, Dec 28 (TIWN): When a man’s lover accidentally chomped his penis during oral sex, it killed part of his member: A black wound immediately began spreading across the head, a case study published this week in the Visual Journal of Emergency Medicine reports.

“Approximately five days prior, his significant other accidentally bit him on the tip of the penis during sexual intercourse,” says lead study author Marc Zosky, a University of Arizona College of Medicine professor, in a statement. “Since the initial trauma, the patient noted the wound to be worsening in pain and became darker.”

The unnamed 43-year-old patient had no fever and was fine when he drove himself to the emergency room — save the dark mass of rotting tissue spreading across his phallus.

The “necrotic post-traumatic bite wound to the glans” resembled a rotting banana — or a scrawl of black Sharpie marker on the tip of his schlong.
