What can I do in this situation?

I'm a senior and this girl I'm dating is a junior. We've gone on two dates so far and she said she likes me. Now last night we were at my friends house watching a movie and we sitting next to each other. We never touched each other or anything. I feel so bad but I know the time will come to "snuggle" together. We haven't kissed yet but we hug when we see each other. I'm wondering how I can sorta give her the hint that I wanna be next to her. Do I tap my foot against her leg during a movie? What kinda stuff can I do? Thanks
