Act like a lady. Respect yourself and he will respect you as well. Real men are looking for lady's not toys.
How do I turn a guy on? How do I get him to be alone with me? Should I wear see-though leggings? How do I act?
Give him long hugs. Put your hand on his arm or knee when talking to him. Physical contact will make him more comfortable with touching you. Wear a thin shirt without a bra. Smile a lot.
To get him alone just ask him to help you with something he's better at than you.
Touch your hair a bit. Move the hair from your face and meet his gaze with a sly grin. Bite your bottom lip sometimes when waiting for him to answer.
Remember, he may not be picking up your hints because you may not be his type . . . Then can be anything from gender to hair color . . . And "turning him on", sends a bad message . . . Moving that fast would communicate that you have had MANY suitors (to put it nicely). If you work with him, this will be the way you will be perceived from that time forward by him and whomever he confides in. It's best to keep the game "a foot" and let things progress . . Naturally . . Maybe cultivate it more slowly . . Would the build up be worth the wait?
