How to flirt with a girl without being obvious as a girl?
Look her in the eyes.
Don't stare off at something else when the two of you are talking. Demonstrate your interest in her by giving her your direct attention. Make strong eye-contact when you are together. At the same time, don't just stare at her without blinking, which might make her uncomfortable.
Touch her gently so you don't startle her. If you two get really comfortable she might even let you slide your hand down a little lower. Once she's comfortable with you putting your hands on her waist, grab her and swing her around. Then, she'll be facing you.
“Making eye contact and holding it just a few seconds longer than a casual glance causes him to take notice of you and start to wonder what you may have meant by that,” says Lieberman. “It's the cool 'silent flirt' that can make him want to know more.”
Keep your touches light and short so she doesn't get uncomfortable. If you two have been having a fun conversation so far, feel free to gently touch her on the hand or on the forearm. Don't go any higher than that, and definitely don't try to grab her waist or anywhere on her torso.
Be direct and tell her that you really enjoy hanging out with her. Be sure she knows you like her for her personality. Keep your eyes on her face while you're telling her you like her and try not to check out her body in an obvious way. Refrain from using sexual innuendos.
Small touches and gestures can be a good sign that a woman likes you. If she playfully pats your arm or rubs against you while you are sitting down, it could mean she wants to be closer to you. She also might want to hug you or be open to an invitation to be hugged.
Smiling at the other person, playing with your hair, and maintaining eye contact are great ways to flirt without physically touching them. If you do want to show your affection through a touch, try sitting close to them and giving a light touch on the arm or hand to start.
If someone smiles a lot when they look at you and connects eye contact with smiling, it is usually because they find you attractive. They might also make fun of you and tease you, or try to make you laugh. If someone's into you, you make them nervous. Their heart will beat rapidly from being around you.
Ask her if she would like to be touched with a phrase like "Can we hold hands?", or move slowly but clearly. Give her a light and casual touch. Brush your arm up against hers, place your hand on the small of her back, or just pass her a pen or a notebook and let your hands linger near each other's.
