The Best Love Advice. Period.

Everyone knows that men's libidos rise with the sun, but women are also likely to have high libidos at the crack of dawn. "Our levels of energy-enhancing cortisol and desire-boosting testosterone tend to be high when we wake," says ob/gyn Rebecca Booth, M.D., author of "The Venus Week". Another reason to set the alarm a little earlier? Morning sex is a natural upper, Booth says: "The high you'll get from the serotonin released can last for hours."

"Good movies inspire," says veteran film critic Leonard Maltin, author of "Leonard Maltin's 2012 Movie Guide". He gave us his favorite smart-about-love picks and the lessons he drew from them. Rent when needed.

"Annie Hall": "Things won't always go your way, but being able to laugh together will keep you strong."

"Moonstruck": "Seeing another couple deal with their crazy families always makes you feel better about your own!"

"The Notebook": "Love can endure any obstacle. And also, every couple needs a good cry once in a while."

"Better Than Sex": "This Aussie comedy shows what men and women don't say—but ought to—before, during, and after making love."

Forget confusing garters and costume-y corsets: Guys really go for that whole "slipping into something more comfortable" idea. "Every year, our top Valentine's Day sellers purchased by men are satin and lace chemises—short, sexy nighties—with matching undies," says Michael Herman, senior vice president of sales at high-end lingerie label Natori. "They just want something that's easy to get on—and off."

Winding down over a Heineken (him) and a pinot (you) when the kids finally sack out is fine most nights. But it's not exactly romantic. We got Kim Haasarud, our resident mommy mixologist, to whip up a recipe that is one part relaxing, two parts sultry, and 100 percent yummy. Seriously, it's like foreplay in a glass.

THE "DO NOT DISTURB"

Fresh ginger

8 oz hot water

2 oz scotch

2 oz honey

Squeeze of lemon

Cinnamon sticks

Peel ginger and slice off 4 or 5 very thin pieces. Heat water and ginger in a saucepan or microwave until very hot. Add scotch and honey; stir until honey dissolves. Strain ginger, add a couple squeezes of lemon juice, divide among two glasses, garnish with cinnamon sticks, and serve.

"The biggest mistake people make when decorating their bedrooms is thinking it's the wrong place for color," says interior designer Cathy Hobbs. "But in fact, nothing sets the mood better." Her suggestion for creating an atmosphere that's equal parts seductive and soothing? "I love a rich sky blue, because it's extremely calming and adds a touch of elegance." She recommends Brave Blue, Malibu Beach, and Neptunes Home, all by Mythic Paint.

A sweet email signature speaks volumes. Here's what a few love-struck readers use:

"I'm pregnant, so I always add 'kisses & kicks.'" —BREANNA WIDGER, VIA FACEBOOK

"I sign mine 'love foreve' with no 'r' on the end, because forever should have no end." —KAREN WARNER MCPHERSON, LANGLEY, BC

"The first time I signed off with a symbol, he mistook it for something sexual and replied with a sexual symbol of his own. That made for an interesting conversation when he got home! But now he gets it." —VALERIE EVERHART SCHULER, VIA FACEBOOK

"'YW,' for Your Wife. It's a discreet, kind-of-secret way to sum up what we mean to each other." —JENNIE TUNG, NEW YORK CITY

Robin Thicke happily acknowledges that his music is of the baby-making variety. But back when first wooing his wife, actress Paula Patton, R&B tunes from groups like Jodeci helped set the mood. So what else does the "Teach U a Lesson" singer cue up when it's time to—Barry White voice—dim the lights?
