So in a few hours, I have a girl coming over my house. I plan on watching netflix on my laptop and on the tv from my couch. If she's right next to me I imagine it would be easy to put my arm around her. However, if things go unplanned, and she sits on the opposite end of the couch, how would I escalate from there? I know this probably seems like an easy question but, Im a beginner.

Thanks a ton

Edit: Ok, so we were laying on the couch, and I put my arm around her and held her hand. For like 3 hours. Then she left and I kissed her, but it was the peck kind. I feel like shit. I always end up being in regret instead of saying "oh well" for a rejection. I really only made this post to try to pump me up, I knew exactly what to do, its just I dont have the nuts to do something. Plus she is a 9+.
