On my dates with my girlfriend we often watch movies or watch tv on the couch or her bed. When we do so she leans against me and I put my arm around her, which is normal right? But when we watch a movie on bed she sometimes acts like she is sleeping and lies down next to/ or behind me. But I don't know what I have to do then (body contact wise)? So normally I just stare at her and wait for her to come back up, because I am too shy to try anything, and know nothing to do in that situation anyways.Any help would be greatly appreciated.
