Gurtuititism
A disease caused by a mosquito carrying malaria flying inside the male penis and biting it, this results in the penis' color changing to green and slowly shrinking over the course of 6-8 months. The disease will also affect your nervous system by giving you the urge to view sexual content more frequently.
I got Gurtuititism and now I really want to watch adult content but my penis is too short to masturbate.
