Unlike that of most peoples of the world, the sexual life of the Etoro of New Guinea gives preference to homosexuality over heterosexuality, although the Etoro practice both. Like many contemporary Hindus, the Etoro believed that males were born with a fixed supply of semen. In the Etoro view of things, maturation for males required first by a mother and then with an older male mentor who taught them the secrets of religion, the skills of art, and the ways of warfare. For religious reasons, heterosexual intercourse was forbidden for as many as 260 days each year (295 by one report), but no such restrictions applied to homosexual relations. The Merind-anim The Merind-anim, neighbors of the Etoro, so preferred homosexuality, that they sustained their numbers only by adoption-through-capture of children into their society from neighboring tribes with whom they warred. The Azande Like the classic Greeks, the Azande of the Southern Sudan, expected homosexual relationships to supplement the normal practice of heterosexually based marriage. As have many peoples, the Azande practiced an age-based system of military service prior to marriage, in effect a form of universal military conscription based on age. During their period of military service, young warriors married boys who played the same roles as female wives played for older men. They provided their husbands with food and drink, brought firewood for their husbands fires, and shared their husbands beds at night. When the husbands grew older, they gave up their boy-wives and entered the heterosexual phase of their lives. In turn, their wife-apprentices graduated into warriorhood and took their own boy-brides.
