It is perfectly natural, all animalbeings indulge in what is refered to as Sexual play, it prepares them for the future encounters with a mate. It has been recorded across countless spieces. It is perfectly natural.
well, ive heard that 90% of giraffe sex is gay :P so...giraffes r gay, lol uhm, what do i think of it? well i know humans are animals, so it's not unnatural that it would happen in other species as well, im not sure why people o animales would be gay or, what benefit it has on the population, heck maybe it helps keep growing populations down? this world is freaking overpopulated anyways, a few gays here and some lesbianas there might not be such a bad thing :P XD
