This behavior is completely Normal, when observed in the young of any spieces it is refered to as Sexual play. Observed in older mga hayop it is homosexuality, this too is Normal!!! And before any christains out there get their knickers in a twist, Man and Woman kind were members of the Animal kingdom last time I looked!
Many mga hayop display homosexual behavior, including bison, brown bears, caribou, domestic cats, domestic cattle, chimpanzees, bottlenose dolphins, marmosets, domestic dogs, elephants, foxes, giraffes, goats, domestic horses, koalas, lions, orcas, and raccoons, kamalig owls, chicken, emu, king penguins, mallard ducks, ravens, and seagulls. Also a lot of fish, reptiles, insects, and amphibians.
Whether it be sex, courtship, affection, bonding or parenting.
I think it's wonderful. <3 The pairs aren't judged sa pamamagitan ng other animals, perhaps humans could learn a thing or two.
