The Etoro, or Edolo, are a tribe and ethnic group of Papua New Guinea. Their territory comprises the southern slopes of Mt. Sisa, along the southern edge of the central mountain range of New Guinea, near the Papuan Plateau. They are well known among anthropologists because of ritual homosexual acts practised between young boys and men of the tribe. The Etoro believe that young boys must ingest the semen of their elders to achieve adult male status and to properly mature and grow strong.
