The Sambia tribe of New Guinea has rites of passage surrounding manhood which involve frequent ejaculation through fellatio. Semen is valued and masturbation is seen as a waste of semen and is therefore frowned upon, even though frequent ejaculation is encouraged. The capacity and need to ejaculate is nurtured for years from an early age through fellatio so that it can be consumed rather than wasted. Semen is ingested for strength and is considered in the same line as mothers' milk.
