A 'move'

When you and your boyfriend/crush go to the movies, sit next to him and during the movie, just start moving your shoulder in towards him until they are touching but not to much. It works for me every time and all girls love the feeling. It,s a great way to break the "touch barrier" without being too obvious. Trust me, He will lean right back. It works for me every time, and it feels like a little spark goes through your whole body, girls love it.
Go ahead and try it, cause it works. '
