Australian jewel beetles and our own non-reproductive sexual proclivities

Donald Hoffman used the Australian jewel beetle as an example of how our senses and even our whole perceptual apparatus are really just a user interface over a universe that we can have no understanding of. I mean, clearly. Look how confused those beetles are as they nearly go extinct making love to beautiful, shiny glass bottles instead of other beetles.

But that got me thinking. What about oral sex? Or pornography? Or simply wearing a condom? People do all sorts of things for fun that are not beneficial to reproduction, or even survival for that matter.

Maybe the jewel beetles enjoy humping bottles so much they don't care that ants are chewing on their junk. How could something so wrong feel so right?

Is there an alien somewhere showing Kink.com to its students to demonstrate how dull human senses are to the actual world?
