To look at them, bighorn rams are the very image of hypermasculinity. They live on the rugged mountain slopes of Montana and Canada, in an environment that demands strengh, athleticism and stamina. Their appearance is impressive, with large thick horns curling back behind the ear, and they’re big, weighing up to 300 pounds. They exude so much machismo, that their image has been appropriated by numerous as a symbol for many male athletic teams. And they like their sex – with other males. Those few who don’t, are described by researchers as “effeminate” .
For bighorn sheep (and also for thinhorns), “natural” sex is same-sex, including elaborate courtship rituals, genital licking, and anal penetration. (Many rams also find a way to “masturbate” – not with their hooves, but by rubbing on the ground.) In this “homosexual society”, almost all rams routinely participate year-round in sexual activity with each other, but heterosexual intercourse is limiting to the rutting season. Even then, not all rams, especially the younger ones, get to participate.
For Bighorn and Thinhorn Sheep, heterosexuality is emphatically not “normal”.
