In general all born under the Scorpio sun are ruled by the planet Pluto and co-ruled by Mars. Pluto rules beginnings and endings of matters...keep that in mind because there is little "gray area" in relationships with a Scorpio whether it be friends, lovers, co-workers, business partnerships, etc...meaning it's either bad or good...and believe me when the dust settles, you'll definitely know which it is. Mars adds the intensity, extremism, drive, sexuality to the character.
So, if you are confused, but interested, about HOW to please a Scorpio you'll need to know what makes them "tick" first and then decide whether you can accept it or not. Don't expect a Scorpio person to "change" for you. Even if they want to make the effort, it's doubtful that will ever happen. Under Pluto's influence they can be nice & sociable--that's the "beginnings" influence AND when it comes to the "endings" influences depending upon the situation at hand, they can not only be abrupt and become downright cruel verbally and physically. When looking at any zodiac sun sign, look at the characterization of what their icon is. With Scorpio it's a Scorpion. Scorpions don't automatically sting what they come in contact with. However, if they consider you to be their prey, they not only stick their stinger into their prey but they twist it to fully and deeply release their venom! Intense and vindictive enough for you?
Each section of a sun sign is called a decanate and it is a span of about 10 days and maybe 4 hours. All sun signs are about 30 days and around 11 hours long.
Those born during the 1st decanate of Scorpio will have a mixed bag of the most intense influences of Pluto and Mars as described above.
Those born during the 2nd decanate of Scorpio have Pisces sun sign influence. So, besides the Pluto/Mars influences described above they are co-ruled by Neptune. The Pisces influence adds some flexibility to the Scorpio nature increasing the gray area. This is possible only because the nature of Pisces (the Fishes) is just like fish normally do...they weave in and out along going in different directions, but when they encounter a challenge; they swim away and take a different path. This more flexible, accepting nature helps fill the up and down gaps in the Scorpio/Pisces relationships. But, please don't be misled because under that milder and more gentle presentation of their character, they are still Scorpions. Just push the issue and you'll see it clearly!
Those born during the 3rd decanate of Scorpio have Cancer sun sign influence. So, besides the Pluto/Mars influences described above they are co-ruled by the Moon. Because the Moon is involved the intense emotional side of this Scorpio they will usually display "extreme hurt feelings and hurt pride". Although the Cancer sun sign will give this Scorpio the nurturing and pampering they will enjoy, watch closely for extreme jealousy and possessiveness, but vindictiveness and retribution.
When studying and practicing the science of Astrology, which is the influence of the planets and their placements in a natal chart of your birth for the day and time you were born....keep in mind that there are many, many more important factors to review than just a person's sun sign. This is what separates the spoof of a blindly written newspaper/magazine horoscope when compared to what an interpretation of a calculated natal chart will tell you. The difference really IS astronomical. (sorry for the pun) Your natal chart is as unique to you as your fingerprints and it is certainly not a generalization.
