I’m looking for examples of what might be called “human fetish”: non-human sentients that by the standards of their culture are perverts who engage in “bestiality” with humans. If it could include the line “with a human?!? ICK!”, it qualifies. Explicitly excluded from this definition is the whole tentacle rape/ parasitic impregnation scene.
Heck, according to various episodes of Star Trek and numerous cheesy '50s sci-fi movies, all aliens want our women.
Hmm…in the 20’s issues of DC’s Hawkworld series, it was revealed that the Hawkman who was active between the end of the Crisis on Infinite Earths and the (then) newly-retconned arrival of Katar Hol on Earth was a Thanagarian spy (Fel Andar) pretending to be Carter Hall’s son, and he took a human wife as the new Hawkwoman as part of his disguise. When the Invasion happened, he expressed disgust about having had to have sex with an Earth woman to keep up his guise.
So Thanagarians - or proper ones, at least - were disgusted at the notion of sex with Earth humans, but I’m pretty sure that both Katar Hol and Shayera Thal had Earth human girlfriends/boyfriends during that series. Whether or not they had gone to bed with them I don’t remember.
If you go to Literotica, they have a category of “non-human” stories.
Yes, but in those stories it’s simply a given that all [del]minorities[/del] aliens want to move up in the world by having sex with [del]white[/del] human women. I’m looking for examples where for the non-human it’s considered eccentric, demeaning, or outright sick.

Well, it’s not porn, but in Dune: the Butlerian Jihad, a robot named Erasmus has a penchant for studying humans in all sorts of “interesting” ways, and is both ostracized and revered for it, alternately. He’s got a real thing for one particular human woman, and is fascinated with the process of her pregnancy. It’s not really worth slogging through the whole damned book, but the bits with Erasmus are worth a read for their thoroughly twisted viewpoint and fascinated study.
Hell, I wouldn’t mind a few myself!
“All your women are us!” :dubious:
From Revelation X: The “Bob” Apocryphon: Hidden Teachings and Deuterocanonical Texts of J.R. “Bob” Dobbs, Chapter 6, “Birth of the True Beautants”:
Can’t seem to find the image online, but I’m flashing on a cover of the old underground series Bizarre Sex Comix: A creature that looks like a bugeyed tentacled walking vagina is crashing through a door, roaring, "Earthman! Give me your SEED!"

No porn in the movie, but since the aliens come to earth as a last resort it is clear that they also thought that going for a female human was a reprehensible thing to do.
Genesis 6:1-4: “Now it came about, when men began to multiply on the face of the land, and daughters were born to them, that the sons of God saw that the daughters of men were beautiful; and they took wives for themselves, whomever they chose. Then the LORD said, “My Spirit shall not strive with man forever, because he also is flesh; nevertheless his days shall be one hundred and twenty years.” The Nephilim were on the earth in those days, and also afterward, when the sons of God came in to the daughters of men, and they bore children to them. Those were the mighty men who were of old, men of renown.”

The OP expressly excludes “tentacle rape.”
I seem to recall reading a sci-fi novel a long time ago – Clarke, perhaps, or one of the many Star Trek novels published in the 1980s – in which the hero (Kirk?) met a sexy representative of an advanced race and she told him that having sex with him would be like having sex with a dog.
Oh man, I didn’t read carefully enough. I thought he was including them.
Well, this is Kirk we’re talking about, so it may not apply to human men generally.
Guess that leaves out the scene from Galaxy Quest.
Larry Niven has some stories that fit the technical definition, although they’re not written as erotica. The humanoid inhabitants of his Ringworld aren’t interfertile, so they frequently engage in interspecies sex. This shows up only in the later Ringworld novels. I recall some other story of his where a flying humanoid wants to 'get it on" with a normal human, but that implies that he has what for them would be a “chubby fetish”.
