You’ve probably already made some resolutions for this year—but did having better sex make your list? If not, it might already be time to reevaluate your goals for 2017. It’s no secret that sex makes you happier—in fact, researchers from the University of Colorado at Boulder found that people who had sex at least once a week were 44 percent more likely to be happy than people who didn’t get down at all.
And like getting fit or climbing the ladder at work, a better sex life does actually take some work. But it’s worth it: Couples who put effort into their sex lives have stronger relationships, new research from the University of Toronto suggests.
So add these 12 new sex positions to your to-do list for 2017. Challenge yourself to try one each month. We promise it’ll be the smartest resolution you’re ever set.
