Matses native men live in a society that is very “macho” in that their practices and rituals often involve enduring pain. That said, there are very few examples of one Matses native man killing another and disputes between men are usually settled in formal wrestling matches followed by spatial separation rather than with violence. Perhaps not surprisingly, the most common cause of conflict between native men is women. Conversely, Matses men are not unusually jealous and spouse sharing is relatively common. However, one must bear in mind that the Matses are polygamous with one native man commonly having multiple wives.
