You are different in many ways: very often, Sagittarius feels light hearted and enthusiastic about some idea, project, plan or dream, and feels that Scorpio is too myopic and stubborn to appreciate optimistic plans. Also, Sagittarius loves festivities and socialising while Scorpio often feels uncomfortable with large groups of people, and prefers a deeper, more intimate involvement with just a few people rather than carousing with a large group. Scorpio is capable of tremendous concentrated and persistent effort whereas Sagittarius prefers to do a little bit of everything: travelling and developing a wide sphere of interests and activities, rather than being limited to a few activities.
Also, Scorpio's feelings usually run much deeper than Sagittarius's feelings, so Sagittarius frequently fails to appreciate the depth of feeling that Scorpio experiences. Scorpio becomes very attached, emotionally, to a love partner and doesn't easily share Sagittarius's attention and affection with anyone else. Sagittarius, on the other hand, is something of a flirt and may innocently arouse intense jealousy in Scorpio. Sagittarius can be weighted down by Scorpio's suspiciousness, demands for loyalty and wholehearted involvement. Worse, Sagittarius may simply ignore Scorpio's needs and not realise how strongly Scorpio feels.
Sagittarius has a much greater need for freedom. The two of you are so different that it will take a lot of compassion and understanding for you to be together for any length of time.
You two are like night and day, emotionally speaking. Sagittarius is light, optimistic, and philosophical about live and emotional experiences, always expecting to bounce back and grow from a difficult time. Idealistic and forward-looking, Sagittarius tends to ignore or deny raw emotion and the dark, painful aspects of life. Scorpio, on the other hand, is an intensely, passionately emotional person who has little emotional distance or detachment. While Sagittarius is basically open, and confides and shares freely Scorpio is very careful, even suspicious, and does not trust or open to just anyone. Scorpio is inward and private and can be quite asocial at times, whereas Sagittarius loves to go out and socialise or participate with people. Scorpio tends to brood and often becomes dark and silent, and Sagittarius may try to jolly or lighten Scorpio up, which can be helpful sometimes but is just as often intrusive. Sagittarius wants sunny weather all the time, while Scorpio loves a storm.
Neither of you are particularly conventional, nor are you great lovers of rules and formal traditions for their own sake, but Scorpio is apt to have a much harder time conforming, and may in fact openly scorn or rebel against such limitations. There is apt to be a great deal of change, constant motion, fluctuating circumstances, and disorganisation in Scorpio's life, whereas Sagittarius embraces necessary changes and flows with them but doesn't seem to need to crate upsetting and unstable situations all of the time. Sagittarius can help Scorpio learn how to be true to oneself and one's own beliefs and nature without needing to always rail against "the establishment" or "the system".
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. As long as you don't end up fighting and competing with each other, you can accomplish a great deal together. However, the aggressiveness of this relationship is prone to foster anger and hurt feelings - so be careful not to incite hostility in each other.
You both love intensity with your sexual expression. Any place, anytime is your motto. You can be very demonstrative sexually, "erotica" is your second name. Impulsiveness may lead you into the sudden and unexpected at times. Sex toys, videos, oils and creams may be your answer to your sexual experimentation.
The two of you have a very powerful and profound effect upon one another for good or ill, and a major temptation for you both is to use your power to control or change or reform one another. Inevitably you WILL be transformed as a result of your interaction with each other and the struggles you will face together, which at times may seem monumental. Circumstances which force you to eliminate everything you thought you knew or had, and begin all over again, will arise. You may lose something which is very precious to you both, but as a result, experience life on a much deeper level.
