I'm a Scorpio and I definitely fit the description:
Scorpio, symbolized by the Scorpion, is a Fixed Water sign. Ruled by Mars (and Pluto), Scorpio is intense, strong-willed, passionate and filled with desire. They are deep, penetrating, complex, mysterious, secretive still waters run deep (Fixed Water). Scorpios love to probe beneath the surface and uncover what is hidden. They are clever, perceptive and almost psychic in their intuitiveness. They are just as emotional as the other Water signs, but their emotions are more repressed kept under cover, hidden. Consistent with their Fixed energy, Scorpios are stubborn and determined. They can be ruthless if hurt and dont easily forgive.
