Not natural in nature? Obviously, you have not witnessed what is natural in nature when it comes to animal sexuality.
Homosexual behavior in animals is sexual behavior among non-human species that is interpreted as homosexual or bisexual. This may include sexual activity, courtship, affection, pair bonding, and parenting among same-sex animal pairs. Research indicates that various forms of this are found throughout the animal kingdom. As of 1999, nearly 1,500 species, ranging from primates to gut worms, have been observed engaging in same-sex behaviors; this is well documented in about 500 species.
Of course one could argue that the average primate or gut worm probably hasn't made a point of studying the hateful ramblings of Leviticus in the bible.
It is not part of natural Animal Behaviour.
You clearly are educated on the subject to some extent.
Animals use the Submissive Rump Gesture to appease a aggressor
Or higher ranking male. There is no actual copulation.
Female animals also use this as a submissive
Type behaviour to each other also.
We as animals are not living in our natural small groups.
We are over crowded.
And just as overcrowded animals or in unnatural living environments
It distorts & corrupts Behaviour.
Also it is a product of wrong imprinting on young children due to
Things like, single parenting, dominant females, feminism,
Our overcrowding, & this Nonsense of accepting & saying its
Alright.
Nature is not in the habit of making mistakes let alone Perpetuating them.
That again is down to our unnatural living environment.
HTH.
