Body language says much more than what you say.

Communication is not always about what you say. What you don't say is much more interesting, because it is often expressed through body language.

Body language can tell you what kind of person you are. Therefore, you should see and understand the most important things:

If a guy licks his lips a few times while you're chilling together, it could mean he's into you. That's because your mouth naturally produces more saliva when you're attracted to someone (again, a biological response). So if he licks his lips a few times during your conversation, he's flirting with you on a subconscious level.

One of the first signs of male body language that suggests he is flirting with you is his posture. If his posture is relaxed, such as standing or sitting with his feet apart, it indicates that he is trying to adopt a macho posture to try to impress you - it's a biological thing.

Have you ever heard of bedroom eyes? They have to do with dilated pupils.

Dilated pupils are an unconscious sign of physical and psychological attraction and pleasure. To find out if he's flirting with you, casually look into his eyes and notice the size of his pupils.

When a guy flirts with you, he will almost always give you constant eye contact. (Plus, it's the perfect opportunity for you to test the size of his gorgeous, dilated pupils.) Now, this doesn't mean that he stares at you a few times here and there, but that he looks you in the eye for at least 3-5 seconds during a conversation. Maintaining eye contact is a sign that he feels connected to you and finds you interesting.

When a guy is flirting with you, he will stand closer to you so that you feel like he is in your personal space. So if you're standing in line together at Starbucks, look at the distance he leaves between the two of you to figure out if he's flirting with you. The less distance he leaves, the more he's into you.

When a man repeatedly runs his hands through his hair, it can mean one of two things: He's flirting with you, he's nervous, or both. And if he feels nervous around you, it probably still means he's into you. But from a flirty perspective, running his fingers through his hair is his way of trying to look good for you.

The next time you're out to dinner or coffee with a guy and you want to know if he's flirting with you, look at his posture from across the table. In a noisy environment, he may automatically lean in closer to hear what you're saying, but if it's quiet enough for him to hear you and he's still leaning in, it's a sure sign that he's flirting with you and that he's paying attention to what you're saying. If he leans in towards you, that also indicates that he wants to be closer to you as well.

Another sure sign that he's flirting with you is when he runs his fingers through your hair. If you have a strand of hair in your face and he takes the initiative to move it out of the way, it could mean that he doesn't want there to be any barriers between the two of you. Running his hands through your hair is also a sign that he cares about you and wants you to feel nurtured by him. Awww......

Sure, many people use hand gestures to get their point or enthusiasm across in a conversation, but frequent hand gestures are also a sign of flirting. When a guy is into a girl, he often uses hand gestures to try to get her attention while he talks. But don't worry if he doesn't use hand gestures. If he has a shy and more relaxed personality, he may not use his hands as often to communicate. Instead, look for his other body language signs like dilated pupils and eye contact.

In a time when virtue is considered dead, gestures like opening the car door for you earn him extra bonus points. And in most cases, he's flirting with you, too. Whether he's offering his jacket, pulling out his chair for you, or walking in front of you to open the door, he's flirting with you and wants you to know it. Since these gestures are all considered flirting, it's also very important to make sure you let him make these gestures.

If he wants to sit on the same side, let him - it means he's flirting with you!

If a guy sits next to you and not across from you in a restaurant or café, it means he's into you. It's his way of showing that he doesn't want distance and enjoys being around you. A rule of thumb of flirting: the less distance he leaves between you, the more he flirts with you.

If a guy is flabby when you're together, it could just mean that he has a bad attitude, but it could also mean that he's not completely sold on you. On the other hand, if he's trying to impress you, he'll usually have a great posture to try to look bigger, stronger, and generally more macho. When he stands tall, he also offers a sense of protection from you. If he wants to protect you, that usually means he also wants to protect other people from coming into contact with you. And what better way to know he's into you than if he doesn't want anyone else to get their hands on you?

If he is flirting with you, he will point his hands, feet or legs in your direction. If he is facing you, it indicates that he is focusing on you and trying to be closer to you. It is said that people tend to point their feet and legs in the direction they want to go. So it only makes sense that if he's into you, he'll be looking in your direction most of the time. He can do this by tilting his chair closer to your direction, or even stretching his legs out under the table, closer to you without you even noticing.

"Guys stop smiling like that at age 5 - unless they're really happy," Wood says. He may not flash a toothy grin during casual flirting, but on a really great date when he's having lots of fun? Watch the teeth: "If he's feeling really happy, he's not hiding it."

If he likes you and likes what he sees, then he wants to see more of it and automatically opens his eyes a little more. This raises the eyebrows.

Someone on a forum asked the question, "What does it mean when a man puts his hand on a woman's knee?" She thought he just wants to make some physical connection with the woman he likes. While some also thought he just wanted to move on others thought that was the way to keep the woman waiting. But no one was 100% right

While this could be a sign that he is keeping his options open, don't be too quick to judge. Anything can still develop from this.

He touches his throat. The throat represents communication and vulnerability, Wood says. If he touches it during your interaction, he's interested in you and afraid to come across well. But context can play a key role here, too: If you're talking to a player, a throat touch could signal dishonesty.That's what men think when they put their hand on a woman's knee.
