Your best tool for seduction isn't a little black dress. In fact, your face can say "come hither" better than any sexy outfit—but only if you know the right expression to wear: The top reason men report not speaking to and flirting with women is that they look unapproachable, according to a recent survey by the dating advice site Wing Girl Method. 

For the survey, Wing Girl Method asked 200 men on Twitter and Facebook what keeps them from talking to women. Turns out, 55 percent said that a woman's standoffish facial expression usually stops them from sparking conversation. What's worse, women usually aren't aware they're giving these unapproachable looks, says Marni Kinrys, founder of the Wing Girl Method and author of Get Inside Her: Dirty Dating Tips & Secrets From a Woman.

"Men don't want to be rejected or fall flat on their faces," she says. "If a woman looks at a guy with a scowl, why would he want to approach her?"

Ah-ha—mystery solved! So how can you fix it? The Guy Next Door, our in-house dating guru, has plenty of tips on how to be more approachable. And when you do get asked out, remember these seven secrets for an amazing first date to make sure there's a date No. 2.
