Couple kissing//"39 Ways to Make Your Love Last and Last"(Photo: Chris Craymer, courtesy of Glamour)

Now that you've fallen in love with someone wonderful, are you wondering how to keep that love alive? Here's what you should be doing as a couple:

...Once a week

1. Fight (a little). Getting your grrs out keeps small annoyances from snowballing. Britain's longest-married couple proves it: Together 81 years, Frank and Anita Milford say their secret is "a little argument every day."

2. Walk hand in hand. Even just to your car after an evening at Waffle House.

3. Compliment each other. This one's a daily to-do, if you can. There's no nice thing that's too small to mention: his excellent taste in music, the way he always opens the door for you — it's all worth a verbal love tap. And he will swoon.

4. Make love (obviously). But also ...

5. Have generous sex. You need at least one sexual connection a week that's all about pleasing the other person. (Dear busy people: Feel free to multitask and make this the sex from before. Same goes for this next one ...)

6. Sleep together before work. Put down the straightening iron and heat things up this way: "Weekday morning sex is the secret sauce in a relationship," says Tristan Coopersmith, 33, coauthor of Menu Dating.

7. Get into bed and ... sleep. "Sometimes the best thing a couple can do to ignite their passion for each other is sleep," says Hillsborough, New Jersey, sleep expert Carol Ash. If you two aren't in the sleepover stage yet, co-napping has been known to work wonders too.

8. Let something go. Argue over the stuff that matters, but once a week let him (and yourself) off the hook for things that don't: Yes, he chews his popcorn loud. No, it won't kill you.

9. Laugh really hard. Laughter is a relationship's Krazy Glue: It bonds you. Uninspired? Fast-forward to the chest-waxing scene in The 40-Year-Old Virgin, or send him something snortworthy from funnyordie.com.

... Once a Month

10. Be do-gooders. Volunteering together (even just helping a friend move) bonds you because you're ID-ing "common values," says Elizabeth Lombardo, a psychologist in Wexford, Pennsylvania.

11. Do something scary. Been together a while? A pounding heart mimics the rush of brand-new love, says Patti Wood, an expert on nonverbal communication in Atlanta. Fly in a balloon, or order the sweetbreads for two!

12. Talk about money. Whether it's "Should we open a joint account?" or just, "Hey, let's split the bill tonight."

13. Brag publicly about him: his fearless pursuit of the mouse in your kitchen, the armful of hydrangeas he surprised you with, the raise he landed even in this economy. Surely once a month you can think of something that'll make him blush in front of your friends. He'll probably get you back too.

14. Declare something "this stays in Vegas." A silly nickname, or a crazy bedroom mishap. Share something intimate, then pull the couple bubble around you tightly.
