Pretty much all animals are gay. They have no religion or morals so it is not "wrong" to them. They simply don't have the intelligence to question it, all they know is it feels good. I would guess humans were this way in the early stages. ( I believe in evolution) Heck we are getting to be that way now[].

My moms little Yorki has a stuffed animal (a duck I think?) that it will hump for hours until it can't go anymore. And that thing isn't even alive or the same species. The dog doesn't seem to mind though. Loves to do it when company comes over.
