An agonophiliac is someone who is sexually aroused by either the actual act of fighting, or watching a combat-based sport-like martial art, kickboxing, wrestling, or boxing. The arousal can even come from simply looking at depictions of the sports or engaging with equipment used in them like boxing gloves, trunks, and mouth guards.
More About Agonophiliac
Some agonophiliacs actually engage in fighting. When that is the case, the arousal can be tied to the energy and outcome of the fight. “Foxy boxing” events where sexy women actually box each other or engage in a highly sexualized context actually play to agonophilia on a large, mainstream scale.
