In what other species in nature to males of the species eschew the females of the species preferring to exclusively penetrate males of their species exclusively ? In what other species in nature to females of the species eschew males of the species preferring instead to ‘fawn on’ females of their species exclusively ? Answer : ( to the best of my knowledge) None . And this is why such behavior goes against nature and can be considered a pernicious form of mass insanity .
IF you believe in God , this is also why this behavior is condemned by God and is repulsive to God . It defies the nature that God ordained .
Actually, it happens in a lot of species.
But “natural law” does not mean “what happens in nature” or “what the animals do.”
