relax, just be yourself man! That way you create a comfortable vibe. Just watch the movie, laugh, make eye contact with her every now and then. And hey, if you want to put your arm around her, then do it. It’s not that big of a deal really. Some girls may say that’s a bold move on a first date, but it’s just a small gesture that you like her, that’s all.
As far as a good time to kiss, that’s the thing: there is no set time as to when you should kiss. You have to be feeling the vibe. If you feel that tingly feeling within and you believe and know by her actions that she might feel the same way, then go for it. It may be during the movie, after the movie, etc.
For example, on one of my dates, the girl was so tense throughout the whole movie and date that I didn’t go in for the kiss. (She was just too shy). That’s why I say it’s important that you relax, so that you can make her feel comfortable and not tense or weird. On another date with another girl, we were at the beach. we were having fun and then spontaneously, I grabbed her by the hands (while we were in the water), pulled her close to me, and told her to look me in the eyes (me trying to figure out if she was feeling the same as I - all weird and gooey inside), then after staring at each other for a few seconds, went in for the kiss. All turned out well.
Like I said, it’s up to you, be aware of the vibe being sent throughout the whole date, but don’t focus to much on it. Have fun and if you feel the time is right, then go in for the kiss.
Alternatively, you could give her a hug first, and if she responds positively, then you might try the kiss. It’s all about reading her and timing.
