Generosity for the win: Focusing on what she craves in the sack also increases your arousal, says research in the journal Social Psychological and Personality Science.

Researchers studied “sexual communal strength”—the willingness to meet a partner’s sexual needs—in long-term couples. Both parties filled out daily sex surveys for 3 weeks. Four months later, generous lovers  reported higher levels of daily arousal AND more desire for their partner than the less-generous couples.

How to Last Longer in Bed

You’ve tried crunching baseball stats. You've mentally replayed your last round of golf. You've outlined the steps to making your favorite sandwich. But the more you try to last longer in bed, the faster you finish—and you’re not alone.

7 Signs She'll Be Good in Bed

It's an enigma as enduring as Mona Lisa's small, knowing smile: Sometimes meek women turn wild in bed; sometimes they just lie there, waiting to inherit the earth.

It made me wonder: Is it possible to reliably predict what a woman is like in bed? The love scientists say yes—sort of.

"It's very hard to gauge," explains Helen Fisher, Ph.D., an anthropologist at Rutgers University and author of Why We Love, a new book about the nature and chemistry of romantic love.

9 Things Some Men Are Too Afraid to Ask For in Bed

No matter how much crazy-great sex you and your partner might be having, admit it: You've wondered if there's any desire he's holding back. Hey, chances are you have a fantasy or curiosity that you may or may not have worked up the courage to divulge just yet, so what's his?
