Cancer + Scorpio
Water + Water = Deluge
People born under the same elements generally feel comfortable with and attracted to each other. This is the case for Cancer and Scorpio. Both of you are sensitive, emotional and caring, but Scorpio has a very different way of expressing love. Scorpio’s love is demanding, and asks a lot more in return than you can give.
Cancer, you’ll feel that you’re showering love and kisses on Scorpio, but it’s never enough. You probably handle the possessiveness of Scorpio better than most signs, because you are an adaptable sign and can comfortably adjust to the Scorpio will.
But Scorpio has to learn to control the desire to dominate and to push people away through sometimes unrealistic demands, both practically and emotionally. Scorpio will use power on any level to get what they want.
Although Cancer and Scorpio are elementally well suited, both being water signs, there are differences sexually. Scorpio is driven by the purely sensual. You, Cancer need love and bonding, not just raw sex.
