I would read the fic where person A knows that person B is from "giant tentacles in every hole you got" planet or whatever, and has been super nervous about getting involved with them because of it, only to discover that they have a microtentacle. And person B worries that people will think he's only with A because he couldn't attract a mate of his own species. But, no, it's TRUE INTERSPECIES LOVE. And no easy fix-its for insecurities and other cultural difficulties, but lots of mutually enjoyable sex with microtentacles.
