Gay

"All men, to varying degrees, have the ability and desire to form affectionate ties with other men. Women have a corresponding ability and desire to form affectionate ties with other women. Attraction to members of the same sex and expression of that attraction is in no way contrary to or an alternative for attraction to members of the other sex. Homosexuality is an emergent quality of individual selection for same-sex affiliation and has been a part of the human experience, perhaps all primate experience, since its inception."—R.C. Kirkpatrick (link)

"Although homosexuality is a widespread phenomenon, in some societies homosexuals confront repression or ridicule. In parts of the United States, for example, public displays of same-sex affection between men in particular are often looked upon as distasteful or even disgusting. One nationwide exception is the football field, where an extreme measure of rough-and-tumble masculine behavior makes it possible for players to pat each other on the behind, exchange celebratory hugs, and even leap into each other's arms without bringing their sexual orientation into question."—William A. Haviland (link)

"Among the most thoroughly homosexual societies known are the Etoro of New Guinea. As reported by anthropologist Raymond Kelly, the Etoro believe that semen is a precious life-giving fluid which each man possesses in limited supply. Without semen, a man withers and dies. They believe that semen can be acquired only as a gift that one male bestows on another. To ensure that semen is properly distributed and used for worthy social purposes, older Etoro men are expected to transfer their semen to young boys. This is done by penis-to-mouth intercourse (fellatio) between seniors and juniors respectively, who sleep together in a village men’s quarters—a separate large house—from which all females are barred."—Marvin Harris (link)
