There's many, many paths to eroticism and sensuality. The human form is beautiful, but there's so much else that's beautiful, too.
This is just human nature. Our closest living relative is the bonobo, not the chimpanzee. Sexuality is every bit as important to who and what we are, as things like tool use, sweat, throwing things, and cooking are. Humans are lovers more than we are fighters. The idea, that upon coming upon a foreign tribe, or strange out-group, that you should greet them, and have sex with them, is part of the fundamental wiring that makes us who we are, as opposed to anything else. Humans have thought and dreamed about meeting strange, non-human creatures, and having sex with them for about as long as we've had the capacity for symbolic thought. Many a creation myth centrally features strange, surreal acts of cosmic fornication, that projects our sexuality on the world around us. Progenitor gods masturbating, or somehow breeding themselves, ideas like the sky fucking the ground, the idea that the singular, primary commandment given to us by an omnipotent creator, is to go have sex. This is just the true form of humanity, you know?
And it's not even like this is entirely hypothetical, either. This has factored into our natural history. If you've spent any amount of time on a horse ranch, you know, that part of the evolution horses have experienced on the road to domestication, is towards sensual compatability with humans. Domestic horses outright prefer human intermediaries. Horses are aroused by human sweat, horse genitals are more tuned to human bodies than eachother, Domestic horses directly breeding has a startlingly high risk of grievous injury, and a high degree of stress to both parties, that just doesn't exist when humans do it, or when undomesticated relatives of horses do it. And that's just the most blatant example.
It's really just been a tiny, anomalous blip on our history to be shy and prudish about this.
