Dear Anonymous Libra,
I'll start from the beginning.
Your Sun Sign is in Libra, but that isn't the astrological reason for your love of Scorpios.
Instead of looking at your Sun Sign to understand why you're attracted to one sign, astrologers look at the positions of Mars, Venus and the Moon in your chart.
In a birth chart, Venus shows how you approach relationships of the heart and the type of people you're romantically attracted to.
Mars, on the other hand, is associated with your sex drive and your physical attraction to someone else.
Finally, the Moon rules over your emotions. If you want to know how someone instinctively reacts or responds to problems, or what someone needs for a sense of security, you should be analyzing their Moon Sign.
Here's where it gets interesting for you, and why I looked up your natal chart to find the answer:
In your birth chart, both your Moon and your Venus are in the sign of Scorpio.
According to Cafe Astrology,
Well, as someone with her Mars in Scorpio and as someone who has dated several Scorpios herself, I can honestly say they're very effective at stirring up emotional excitement.
Having your Moon in Scorpio does give you the ability to see right through people's bullshit, and so it makes sense that you would find yourself attracted to Scorpios, who are the most mysterious sign in the zodiac.
You can know a Scorpio for years and still feel as if you haven't even scratched the surface of what they're really about.
Having your Venus in Scorpio doubles the intensity of your attraction to people with this Sun Sign because it indicates you want exactly what they want and exactly what they have to offer.
With Venus in Scorpio, you desire and crave a deep, intense and passionate relationship.
In love, nothing short of a merging of souls will satisfy you.
The bonds you form are strongly emotional and could be jealous or possessive because you essentially want to own your lovers completely.
You love deeply, almost painfully.
Because you're aware of this tendency (Moon in Scorpio endows you with great self-awareness), you're able to control your passionate emotions until you are fully able to trust someone, but there's a power play in this.
You won't fully give your heart to your partner until you know they've basically surrendered theirs first.
So, to return to your question, "Is there a reason for this?"
Yes, there is a reason.
Then again, if you think astrology and horoscopes are bullshit, it could be you're just into dudes who remind you of your dad.
