"Among Sambian males of New Guinea, young boys begin with sexual activities with older boys. Sambians believe that a boy can grow into a man only by the indigestion of semen, which is, they say, like a mother's milk. At adolescence, their role changes, and they must provide semen to boys to enable them to develop. At first, they worry about their own loss of semen but they are taught to drink tree sap, which they believe magically replenishes their supply. After they become fully involved with adult women, they lose their desire for men."
