Human-Alien pairings, where the male is extraterrestrial and the female human or close enough.

As the title says, this list is for erotica books with aliens (or basically books that have sex involving 1 or two or more aliens... and a decent plot). I'd appreciate if the book also had a great plot or any plot at all, not just a continuous sex scene (not there is something wrong with that, but having a decent plot also helps). Which means, no platonic hand holding, no vague, 1 paragraph sex scene and most importantly, no confusing regular PNR or Fantasy books with Sci-Fi just because you thinking that being a werewolf/vampire/ghost/god/cyborg/whatever automatically means being an alien a.k.a. an extraterrestrial.

It does not. Hint: you usually have some spaceships, other galaxies, some unfortunate crash-landing, the occasional space pirate or alien overlord, maybe a few kidnapped humans (usually females, because reasons), aliens with very interesting anatomy, etcetera, etcetera.

Or worse, randomly adding and voting on this list for books like Twilight, The Hunger Games, 50 Shades etc.

No YA or M/M books as well. But if you do add them for some unknown reason (like being very drunk while browsing Goodreads, or to boost popularity in the very annoying way), they will be deleted ASAP.

In case you're still confused about what Alien Erotica with an actual plot is, I suggest you check out R. Lee Smith's books. Or Poppy Rhys's. But R. Lee Smith is generally the queen at this.
