The 2 Zodiac Signs You Have The Least Romantic Chemistry With, Based On Your Sign

Andrew Zaeh for Bustle

When you don't click with someone, there are usually a few factors involved that are keeping you from having romantic chemistry — including how their zodiac sign meshes (or doesn't mesh) with yours. So if you've been wondering why you aren't feelin' it with someone, despite wanting the relationship to work, this may help explain why.

"Each sign has associated personality traits, and some signs have contrasting ones. Personality clashes come from each sign’s idiosyncrasies," professional astrologer Rachel Lang tells Bustle. "These are often driven by an individual's deeper needs, wants, or life focus." If your partner's needs and wants don't line up with yours, it can feel like the relationship is constantly strained.

"That said, there are so many factors other than just the sun sign that make up a person’s natal chart, and astrological compatibility is a complex process," Lang says. "Even if your significant other is a contrasting sign, you can still have an amazing relationship. Sometimes contrast facilitates growth, and we can become very attracted to those signs opposite [...] from our own."

And, of course, there are many things you can do as a couple to improve your connection, if you'd like to make it stronger, healthier, and happier. For some signs though — like the ones listed below — it might just be a little more difficult.
