Your natures are so different that you are bound to clash at times. Very often when Sagittarius feels the urge to travel, explore, expand, and follow a new star, Cancer feels just the opposite: the urge to be close to family, to establish roots, to have children and provide for them, to be near close friends. Sagittarius's desire for freedom and exploration is often at cross purposes with Cancer's need for security.
Sagittarius tends to also be philosophical and detached about personal matters while Cancer takes a much more personal, subjective, compassionate, and emotional approach to life. Although in theory your differences can complement each other, and sometimes they do, there are times when you will have to be very creative and imaginative to find ways to meet everyone's needs.
Your emotional needs and temperaments are quite different, and this creates frustration for both of you, or at least discomfort at times.
Cancer is inwardly tender and sympathetic, and has a great yearning for closeness, and a sense of belonging or security.
A very sensitive and feeling person, Cancer can be quite moody. Feelings of nostalgia, longing, melancholy, crabbiness, and worry or anxiety are a part of Cancer's emotional nature. Sagittarius on the other hand, is cheerful and upbeat most of the time, and is frequently impatient with Cancer's moods and insecurities. Sagittarius may try to intellectualise or philosophise Cancer out of feeling moody. Rather than accepting Cancer's feelings, Sagittarius will either ignore them entirely or try to lighten them up. But in either case, Cancer ends up feeling misunderstood or simply not accepted.
Also, Cancer has a strong concern with, and attachment to, the past, while Sagittarius is forward-looking and concerned more with the future. Cancer is domestic and needs a strong, secure home base, while Sagittarius yearns for the new and unfamiliar. Sagittarius is more adventurous and more willing to uproot and change residences in pursuit of growth and opportunities, and Sagittarius doesn't want to be completely possessed or tied down. Freedom, mobility, and a certain degree of independence are essential for Sagittarius, who may feel dragged down by Cancer's neediness, emotionality, and need for roots.
Furthermore, Sagittarius is naturally quite candid, frank and rather tactless. Sagittarius doesn't take everything as personally as Cancer does, and often hurts Cancer's feelings unintentionally. Sagittarius may feel that natural self-expression must be inhibited in order to accommodate Cancer's over-sensitivity, and this can be frustrating.
Positively, Cancer can benefit from Sagittarius's humour and optimism, and Sagittarius may learn to acknowledge and accept innermost feelings more fully as a result of being with Cancer.
This is likely to be a stormy and fiery relationship. The romantic attraction between you is very strong, but your feelings are often not in tune with each other. One of you (typically Sagittarius, but sometimes Cancer) may feel sexually aroused by the other and consequently be too aggressive in approach, while the other person feels great love and affection, but is not feeling as sexually attracted. Jealousy and possessiveness are also likely. Feelings can swing back and forth and you may not realise how much you love each other until you are away from each other.
This is a passionate relationship, but also a rather aggressive and combative one at times. Sex may be a bit rough, crude, or insensitive as well. You stimulate each other both in sexual and non-sexual ways, but you are also inclined to irritate each other. You may find it difficult to respond confidently in a sexual relationship together. Sagittarius may take more than Cancer is willing to give. Selfishness and mood swings can put a damper on your sex-life.
As a couple, you generate a lot of positive energy, enterprising ideas, and a belief that you can do anything you really want to. You reinforce the encouraging attitude that what you do can really make a difference. Confidently acting upon those beliefs produces successful results in the world. A sense of ambition and enterprise infuses your relationship. However, minor achievements or humble successes, and even some of you grander accomplishments will not be enough for you. You'll always be seeking the next challenge, the farther horizon. The two of you must join forces and work together for some mutual goal, for you're apt to feel restless, discontented, and dissatisfied when you aren't doing something. A good bit of healthy, friendly competition between you will invigorate and challenge you both. Sports or outdoor activities would be good outlets for your combined energies.
