He Maintains Eye Contact A man will prolong eye contact with a woman he finds appealing. Also, pay attention to his pupils; pupil dilation is an indication of sexual attraction and interest. If he maintains eye contact and his pupils are dilated, there is a good chance he is interested in you.
He Tries to Attract Your Attention This behavior can range from a subtle tie adjustment to a loud and boisterous display. Any exaggerated movement or gesture while in your presence suggests that he is trying to get your attention.
He Engages in Preening Behavior A man who is interested will smooth his hair or straighten his tie in order to look good for you. If he exhibits any type of preening behavior while interacting with you, it is a sure sign of attraction.
He Touches His Face While Looking at You When we are attracted to someone, our skin becomes increasingly sensitive to touch and other stimulation. If a man is interested, he may stoke his cheek repeatedly with his fingers or rub his chin. This behavior is a combination of nervous excitement and autoerotic touching and suggests that he is attracted to you.
He Touches You The brief touch may appear accidental at first, but it's really just his way of showing interest. For example, his fingers may brush up against yours when he is handing you an object; or when standing side-by-side, he might "accidentally" bump into you. Any type of touching behavior indicates interest.
His Eyebrows Remain Slightly Raised While You're Talking If his eyebrows are slightly raised upon meeting you or during conversation, it means that he finds you fascinating. People subconsciously raise their eyebrows and open their eyes wide when they are looking at something they like. This allows their eyes to take in more of the object that is so appealing.
He Stands Up Straight Men tend to stand up straight and display their muscles when they are in the presence of a female they find attractive. If his hands are on his hips, it's another sign that he is interested. A man will stand with his hands on his hips to emphasize his size and body confidence.
