One of the best things about being in a relationship can be having someone with whom you can wear sweatpants, burp, not shower for days, and still be loved. However, there's something to be said for hot-and-heavy passion, too. Although it's totally normal for passion fizzle a bit after the honeymoon stage, for some, that fire only grows over time. I've rounded up the zodiac sign pairings with the most passionate relationships, and for these couples, passion is rarely a passing phase.
There are some zodiac sign pairings that have great sexual chemistry but nothing in common outside the bedroom. Then there are pairings who make totally affable partners but inspire less arousal than most peoples' grandparents. Sure, having a bar trivia night and pizza-eating pal for life is pretty awesome, but IMO, that can also be what besties are for. Of course, a relationship doesn't have to entail toe-curling, headboard-rattling passion in order to be successful. It's also natural for that heat to cool down once you and your SO become more comfortable with each other. But if you're looking for a boo with whom you can create some serious sparks, then maybe you'll be lucky enough to find yourself in one of these steamy zodiac sign pairings.
