I think I'd wanna put my arm around a new girl before I kiss her for the first time--I'm too nervous to just go in for a kiss. I'd do it while we're taking a walk on the first or second date, while watching a movie, etc. Is it a good idea?
And how do I know if she'd like that? How can I be sure that I'm not awkward about it? I'm shy and awkward around girls, but in rare moments I can be confident. Thanks. : )
I agree, if the date has been going well and you get the sense that she's comfortable around you. Just go for it. You could start with softly brushing her back. Often we women just wait around for the man to make the first move. We might try to walk close next to you or sit close, casually touching your arm ect ect.- hoping you'll make a move, That would be a great time to put your arm around her.
And if she doesn't like you touching her, you will know- if her body tenses up or she might even tries to squirm away.
Look at her pupils. If she stares right into your eyes and her eyes are opened wider then normal(dilated) then she is feeling sexual and wants you to kiss her/hold her/have sex with her. Also some more useful information is if her pupils are closed don't start anything with her lol. She is either apathetic, sad, or depressed.
