Not to sound gay or anything but I found this old drawing and connected it to something
So apparently, to be uranic is to be sexually attracted to sexualities relating to the male gender, and being neptunic is to be sexually attracted to sexualities relating to the female gender. Notice how Sephiroth, a male, is holding Uranus while Sayori, a female, is holding Neptune
Note to self, everything I mentioned is purely coincidental and I wasn’t thinking of sexualities back when I was actually working on the drawing
