When Fish was just 12 years old, he met a boy who introduced him to coprophagia (consuming feces) and urolagnia (drinking urine). Fish had also begun to frequent public bathrooms where he would watch the younger boys undress in front of him.
Later in life, his fetishes became more powerful as he turned to self-mutilation. He asked his own children to repeatedly hit his behind with various objects. Notoriously, Fish was known for pushing needles so deep into his groin that they could not be removed. An X-ray of Fish’s groin with 12 needles embedded deep under his skin was shown during his trial.
In court, psychiatrists testified that Fish’s sexual fetishes included sadism, masochism, exhibitionism, cannibalism, coprophagia, urophilia, pedophilia, and infibulation. Fish said, “I always had a desire to inflict pain on others and to have others inflict pain on me. I always seemed to enjoy everything that hurt.”
