There are plenty of famous interspecies couples throughout Sci fi and fantasy. Personally I like this trope because I am a sucker for science fiction that deals with the possibility that we can get along with each other, I am a sucker for romance, and I firmly love the idea of love conquering all.
But as a writer and a world builder I want to try and figure out how to update this trope into something more...realistic. Because in fiction it is usually portrayed as a human and humanoid pairing up. But I am of the belief that the humanoid body plan will be a rarity meaning that most interspecies newlyweds might look something like this.
Don’t they make a lovely couple?
Now I do not believe that any difference in body-plan will be enough to dissuade all humans away from such courtships. I spend far too much time on the internet to ever believe anything that foolish.
So the question is: how would Interspecies couples work around alien body-plans to continue successful loving relationships?
