Sagittarius dating another sagittarius
To fully understand someone or how compatible you are with them we need to calculate those other planet placements from their date of birth, and compare them to your own, and then interpret the results.
This unlocks the real power of astrology, and gives much more useful and specific information: everything from how they view you, how to turn them on, how to avoid arguments with them etc.
As counter intuitive as it may sound, this may lead your partner to feel you're sometimes flighty or even shallow, while you may find them somewhat obsessive (the irony being that neither of you are guilty of these accusations) Whether you ultimately make each others head hurt or enjoy the contrary perspective remains to be seen.
You do have a lot in common though meanwhile: You both tend to have a great sense of humor, you're both outgoing and always looking for mischief or adventure to keep things interesting.
Intelligent, outgoing and philosophical - their fast mind, inquisitive nature and fun personality will draw you in.
You have much in common, for one you both enjoy stimulating conversation.
Similarly, while you enjoy listening to the opinions of others and evaluating each based on its merit, your Sagittarius tends to be much more self opinionated.
Similarly, your Sagittarius may at times get frustrated that you don't adopt and defend a viewpoint more - they often prefer a friendly debate over purely sharing ideas.
