They say up to 90 percent of our communication with one another is nonverbal — but is he getting the right message? Sometimes what’s in your heart and mind doesn’t come across in your body language. When dating and mating, it’s important to make sure your body language is as sharp as your conversation skills.

From first impressions to first dates, a smile can be worth a thousand words. A smile conveys warmth and friendliness, and helps put the other person at ease. Eye contact is another body language biggie — direct eye contact shows your respect for the other person, as well as your interest in him. In fact, if you want to show a man you’re really into him, look deeply into his eyes as he speaks to you. Trust me — he just might forget what he was saying! To catch the interest of a guy who you’re not on a date with (yet!), catch his eye and smile. Then look away. Hold his gaze the next time you glance over.

Other signs that convey your attraction include leaning toward a person, tossing your hair (not playing with it), crossing your legs, and lightly touching your arm or your neck. When people are really attracted to each other, they often lick their lips.

If you’re wondering about him, similar rules apply. Some signs to watch out for? Fidgeting, crossing his arms across the chest, and darting eyes are all signs of indifference or worse. If he can’t stop scoping the room, it’s probably best to move on!
