7 Sex Upgrades for Your Bed

The whole "twin  bed with threadbare sheets" thing may have worked in college, but you’re out of the frat house now—which means your bedroom needs to grow up, too. “Surrounding yourself with warmth and luxury is a catalyst for sex—an aphrodisiac, even,” says Cathy Hobbs, an interior designer in New York City. “It’s the difference between being at Motel 6 and the Four Seasons.”

Make your bedroom a place where women want to jump between the sheets—and stay there—with these seven tips. Then hang up the “Do Not Disturb” sign and get busy.

Could Porn Cause ED?

One out of  every four new erectile dysfunction patients is under 40, according to a recent study in the Journal of Sexual Medicine. That’s compared to a 2002 Dutch review that found just 2 percent of younger men suffer from ED.

What explains this apparent spike in bedroom-related blues? Theories range from higher rates of stress to greater honesty in reporting the issue. But some research suggests your online porn habit may also play a role.

7 Reasons She Breaks Up With You

Breaking up isn’t always hard to do. Sometimes it’s really, really easy—like when a girl realizes she's dating a cheater. But sometimes the reason a relationship ends isn't as clear. That's why I compiled a list of women's dating dealbreakers. Commit any of these crimes, and you'll send her running for the hills before the relationship even begins.

You flirt with her friends.
The only thing worse than checking out another woman in a girl’s presence is hitting on one in her inner circle. Even if it’s playful, it’s a turnoff. Sure, she’ll love that you can hang with her group, but she doesn’t want to wonder if you’d rather be hooking up with her leggy friend. Be nice to her girlfriends—but give her your undivided attention. After all, she wants to know you only have eyes for her.

4 Financial Sins That Ruin Relationships

Hooking up with  another guy might seem like the worst way she can cheat on you. But what if she borrows your credit card and fails to mention it? If you suspect the woman you are with lies about how much she spends, saves, or borrows, it could be ruining your relationship.

In fact, one in three adults who have combined their finances in a current or past relationship admit to committing financial infidelity, reports a recent online survey by the National Endowment for Financial Education. And it turns out this type of cheating has serious consequences—76 percent of respondents reported that financial deception hurt the relationship, 10 percent reported it led to divorce, and 8 percent claimed it led to separation.

Do You Really Need Deodorant?

Some guys may  think their sweat doesn’t stink like everyone else’s, but ask their girlfriend or anyone near them in the gym and you’ll probably hear a different story.

The truth is, some people do give off fewer odors than others—but everybody has some sort of trace: “Body odor is determined by environmental factors, like what foods we eat, and genetics. Some people just smell stronger naturally,” explains Robyn Gmyrek, M.D., director of cosmetic dermatology at Columbia University Medical Center. But it’s not the actual dampness that smells. The bacterium that breaks your sweat down into organic compounds is what has that potent stench, she adds.
