Male big horn sheep live in what are often called “homosexual societies.” They bond through genital licking and anal intercourse, which often ends in ejaculation. Giraffes have all-male orgies, as do bottlenose dolphins, killer whales, gray whales, and West Indian manatees. Macaques are ardent lesbians who have sexual encounters every two hours. When male bonobos are not giving each other genital massages, they engage in “penis fencing,” which leads to ejaculation. So says Seed magazine, anyway. (t/y Beau)
