He leans in toward you as you speak. He takes any opportunity to touch you. He rubs his chin or the back of his neck (to release pheromones). He deepens his voice or becomes more expressive when talking to you.
Men might grab a woman's shoulder or pat a hand. Women might brush their hands or give a playful tap and a laugh. Touching shoulders or legs (if seated), ever so slightly, is another flirtation cue.
Guys flirt with girls they like. He might ask you for your number, then call you the next day. He may act playful, wink, and flash a smile at you. If most of your conversations feel flirty, then odds are that he likes you as more than just a friend.
The clues aren't always obvious, but you can see some of them by paying attention. When someone finds you physically attractive, it shows by always making eye contact, always wanting to touch you physically, and frequently initiating conversations.
How Do Guys Sit When They Like Someone? Paying attention to a man's body language clues can help you decipher whether he is interested. If a man likes you, he may sit facing you with his legs spread open. This indicates that he is open and receptive to you.
If you notice he is making more eye contact with you or you catch a guy staring at you, he is probably attracted to you. He may be enthralled by your good looks and may be fantasizing about kissing you. Perhaps he stares at you and smiles; that could mean he likes you, too.
Any person that likes you will want to touch you all the time, and not in a intrusive way, but more of a sensual one. And when a guy touches you a lot, it's usually pretty evident that he's really into you. If you feel the same way, then go ahead and touch them back.
If he compliments your eyes, the color of your hair, your laugh, or an admirable aspect of your personality, then he's definitely flirting with you. He may even tease you a bit while flirting with you, like if he says something like, "That's the brightest sweater I have ever seen," but he's still flirting with you.
He can't stop asking questions about you
If a guy can't stop wanting to get to know, he's probably into you. Questions show he is curious and interested. He wants to learn about you. He wants to understand what makes you tick.
Seeking your approval is a huge sign he likes you.
If he solicits your advice, asks what you think, or tracks your reactions, it usually means that he really wants to know how you feel about him! A friendly guy may not necessarily care about how you feel about things they do or say.
1) His eye contact is strong
He keeps glancing over and when he catches your eye he holds his gaze for a long time. Maybe it's the guy who checks you out from across the bar or your colleague who always makes eye contact when you pass by him in the office. Notice how he looks at you.
This feeling is what we usually call chemistry between people, or "the spark"—a twinkle in the eye, a skipped heartbeat, or flushed cheeks that indicate two people are truly connecting.
Your cheeks flush, palms sweat, and heart races
“This can lead to having a physical sensation of craving and the desire to focus your attention on that specific person,” she says.
Catch their eyes on you.
If you catch them often staring at you, or even simply stealing glances – there is a good chance that they are interested. People tend to stare intensely for 2-3 seconds at people to whom they're attracted, then lower their eyes and quickly look away.
If a boy really has a crush on you, then he'll be likely to give you all of his attention. He'll turn his body toward you, make eye contact, and won't look around for his other friends or text them during your conversation (unless he uses his phone as a crutch because he's nervous).
During the flirting stage, a guy who likes you will attempt to show you his best sides. He'll talk about his new apartment, his band, his promotion, or his talents. Some men may even shower you with expensive gifts, invite you to watch them play a sport, or make an extra effort to improve their physical appearance.
Being a good listener and having intellectual conversations. Although for any man, the primary attraction has a lot to do with the way a woman looks, it is equally important for him to be able to converse with her on an intellectual level.
He remembers everything about you and tells you so
He wants you to know that he has been hanging on to your every word, that he's interested in you, and is a good listener. If you reckon he could take a quiz on everything about you, he is probably trying to flirt with you, and show you he cares.
