The Etoro believes for a boy to grow and become a strong male adult they need to to be feed with an older male semen.
Bizarre homosexual rites are practiced extensively by numerous Melanesian tribesmen in New Guinea and adjacent islands.
Young boys must "accumulate" semen for several years, either by regularly receiving anal penetration, or by swallowing the ejaculations of older males.
This ancient custom springs from a religious belief system that regards sperm as the essential channel of masculine energy; puny boys, they believe, are only transformed into virile warriors if they ingest large quantities of sperm.
They are well known among anthropologists because of ritual homosexual acts practiced between the young boys and men of the tribe.
The Etoro believe that young boys must ingest the semen of their elders daily from the age of 7 until they turn 17 to achieve adult male status and to properly mature and grow strong.
The Marind-anim of Southwest New Guinea -- who were ruthless headhunters -- give the boys to maternal uncles who penetrate them in anal intercourse for six years.
The nearby Jacquai tribe refers to the adult penetrator as "mo-e" (anus-father) and the receiving child as "mo-mog" (anus-son). Big Namba chiefs of the New Hebrides Islands have numerous boy lovers; the Keraki of the Papuan lowlands sodomize lads at a bull-roarer ceremony; and the Great Plateau Kaluli "engage" youths to older men selected by their fathers.
Many tribes -- like the Etoro of the Papuan Plateau -- claim that semen does not even exist in boys until it is orally or anally "planted."
This myth seems valid to tribesmen because boys start ejaculating when they achieve adolescence -- they are allowed to penetrate younger boys then, to maintain the tradition.
The Etoro Tribe:
Well while you might find this disgusting, men of Etoro smile say drinking a semen from a stronger man show how strong you will be when you grow.
