10.Among some cultures, such as the Hopi in Arizona, the Wogeno in Oceania, and the Dahomeans and Namu of Africa, masturbation is encouraged, including regular masturbation between males. In certain Melanesian communities this is expected between older and younger boys. One interesting twist is the Sambia tribe of New Guinea. This tribe has rituals and 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.[
Other cultures have rites of passage into manhood that culminate in the first ejaculation of a male, usually by the hands of a tribal elder. In some tribes such as the Agta, Philippines, stimulation of the genitals is encouraged from an early age. Upon puberty, the young male is then paired off with a "wise elder" or "witch doctor" who uses masturbation to build his ability to ejaculate in preparation for a ceremony. The ceremony culminates in a public ejaculation before a celebration. The ejaculate is saved in a wad of animal skin and worn later to help conceive children. In this and other tribes, the measure of manhood is actually associated more with the amount of ejaculate and his need than penis size. Frequent ejaculation through masturbation from an early age fosters frequent ejaculation well into adulthood.
