1) a penis that has not been properly treated after an encounter with a mold infested vagina. The penis in question must be kept in a state suitable to mold growth. IE the person does not wash the penis, yet occasionally gets it wet while refuseing to see a doctor to get the mold infection removed.
Please note that a moldy penis is not allways noticed by the mold. Leaky faucet syndrome is a common precursor to the mold surrounding the penis and perhaps within the penis. As with all stds know your partner. The number of partners a person has had directly correlates to the prevalence of moldy penis syndrome.
