A taint male is a slang term for the perineum, which is the tissue located between a mans ball sac and his butt hole. The perineum is a small patch of flesh located between the penis and anus. It is an erogenous zone that contains multiple nerve endings that help with sexual arousal and response. The term "taint" is derived from the old saying, "Taint your balls, taint your ah*le". The perineum is a sensitive area that can be stimulated to help men achieve orgasm. It is also a prime location for swamp ass to take its toll, making it important to keep clean and dry.
