Call it a sixth sense, good gut or intuition, but whatever the name, the Crab has it. Members of this sign have an excellent instinct for which partner will serve them well, and once they hone in, it's a laser beam shot. Cancer's charm and magnetism are qualities which will prove most alluring to a lover, and coupled with their nurturing need, will prove hard to resist. The Crab loves to feel secure, so a lover who remembers birthdays and other special days, or simply pops a bottle of champagne for no special reason, will be rewarded with tenderness and affection. If the Crab tests a lover with occasional bouts of jealousy, it's only because a stronger emotional response is craved. The ideal Cancer soulmate can spoon on the couch and watch TV all night long.
