Zodiac Compatibility with Water and Earth, but rarely Air Signs
Anyone that has loved a Fixed Sign knows they have a lover for life, and this certainly rings true for Scorpio. That is not always a great thing, as if any sign is going to go "Single White Female" it's going to be Scorpio. But you can't beat the passion and sex appeal from this Fixed Water Sign. Scorpio needs someone that accepts their intense emotionality, and they don't usually find this with the thinking Air Signs.
But Scorpio can make some sparks and steam with the Fire family so long as everyone is putting the effort in. At the end of the day, Earth Signs stabilize Scorpio's intensity, and Water Signs just "get" you like nobody else will. And that's really all Scorpio wants after all.
