One problem with this pairing is that it can be too "hot." The passion that the two individuals have may lead them to look outside of the relationship.
While they are both loyal, and typically won't cheat on the other, if their relationship should begin to lack passion, excitement, and purpose, the Capricorn woman may become dissatisfied, and the Scorpio man may become bored.
He may be arrogant and tough headed but it is easily forgiving when his affection grows above and beyond such arrogance. This coupled with his sentimentality makes him an incredible, passionate and sensual lover who is always ready to shower his lady love with affection and care.
But his sense of superiority is comes above all and he demands full devotion in return of his love.
A Capricorn woman, no matter how proper she may appear the others, has an earthy and robust sexuality.
