How to make him want me?

One trick that has always worked for me is the knee touch. Sit close enough to him and when he says something funny, laugh and tap him on the knee and let let your hand linger for a little bit. And always make eye contact but not too much to where he'll think you're psycho. Also, just in conversation ask if he has someone special. If he says no, then say "Well I can't imagine someone like you will be alone for long." Good luck!!
