Girls what was she trying to hint? Could I have done more in that situation?

One of the beautiful girls in the class sat beside me and the whole class she was sitting in a pooping up high position. She doesn't do it with any other guys. at the end of the class she was proactively running her hands all over her thighs. Was that a sign that she was sexually attracted in me and want me to touch her thighs?
