Okay,this seems a little creepy at first,but just hear me out. Whenever I want to impress or charm someone (not just guys,but anyone),I do a little physical mirroring. What this means is taking whatever physical action that person does,waiting about five seconds,and then copying the motion. For instance,if your guy rests his elbow on the table,wait five seconds,and then put your elbow on the table. Sounds silly,but it works! It creates a connection between me and the guy that he just can’t explain. Read more about mirroring here.
