In astrology, when a Cancer man is in love, he reveals his sensitive side and is extremely affectionate. Cancer the crab is a water sign, and both Cancer men and women tend to be very emotionally open. Cancer men are most compatible with Cancer women, as their sensitive personalities complement each other nicely.
Cancer men crave stability, and they are extremely protective of their mates. Cancer men are often referred to as "mama's boys" because they tend to have extremely close relationships with their mothers. This close bond with the feminine side is what drives the Cancer man's sensitivity. With Cancer men, there is no mystery. When they feel strongly about someone, they let their feelings show.
When Cancer men are hurt in relationships, they tend to recoil for extended periods of time. Once a Cancer gets burned a lover, it is hard for him to trust again. They are sensitive dreamers, and broken relationships tend to upset their delicate balance. Cancer men are not afraid to cry, and marriage is extremely important to them. Cancer men choose their partners carefully due to their sensitive nature, and when they finally meet "the one," they treat her with overwhelming kindness and respect.
