"Pay attention to his touch. A man who is interested will find any excuse to touch you. This could be anything from simply touching your arm when you say something funny to reaching over and brushing an eyelash off your face.
Where he touches you is also important. If your date is trying to flirt with you, he'll make a point to touch your back, upper thigh/arm, or your sides.[9] He also may try to grab your elbow to guide you through a crowd, showing you and everyone else that he's with you. [10]"
"He offers you his hand palm-up. If you're at the hand-holding stage, pay attention to the way he offers you his hand. If his palm is facing up, he's hoping to connect on more than just a physical level.[14]"
Gage his giggle-factor. Does he laugh easily around you? A man who is attracted to and comfortable around you will laugh more easily than a man who could care less. In addition, he may try harder to make you laugh or get you to notice him
Take careful watch when he is standing near you. He may try to move in closer when you don't seem to be watching to test if you feel comfortable around him. In normal conversation, a man will be 1.5-2 feet away from another person. [16] If he is closer, you can take that as a sign that he's attracted to you.
