7. Your Partner Makes You Laugh

Laughter can make for some great chemistry (and some lighthearted fun, of course.) "Chemistry can peter out quickly, but if your partner makes you laugh, or you do other chores together and adore one another OUTSIDE of the bedroom as well as inside, those are clues that your partner and your passion will not fizzle out," says celebrity matchmaker and relationship expert, Bonnie Winston, over email with Bustle.

If you have any of these habits and behaviors in your personal relationship, you're in luck. There's tons of promise that you and your SO will stay happy and intimate for years to come. (Which is what everyone wants, right?)
