Fungus Dongus
A bacterial infection that encompasses the male genitalia and often spreads up into the anus resulting in very intense stimulation. The only cure for this is to ejaculate into your own anus requiring at least 4.5 inches flaccid, though most often it’s preferred to not cure the infection and enjoy intense orgasms.
