“must fellate their elders”? Ingestion

Cultural practices
In some cultures, semen is considered to have special properties associated with masculinity. Several tribes of Papua New Guinea, including the Sambia and the Etoro, believe that semen promotes sexual maturation among the younger men of their tribe. To them, semen possesses the manly nature of the tribal elders, and in order to pass down their authority and powers, younger men of their next generation must fellate their elders fellate their elders and ingest their semen. Prepubescent and postpubescent males are required to engage in this practice.[40][41] This act may also be associated with the culturally active homosexuality throughout these and other tribes
