If a girl touches you in these places, is it flirty?

Anonymous
What if she touches your arm in a casual conversation, I mean is there any reason to touch a guys arm unless you're trying to be flirty?

How about a guy's chest, is that flirty if a girl lightly touches the middle of your chest as you two are talking?

How about a guy's hair? Or a guy's face?

I know (as a guy) I keep my hands to myself if I don't want to give the girl the wrong impression. It doesn't take much, just being nice and touching someone, to make them think you like them (in my opinion), so I figure gotta be careful not to lead anyone on.

So which of these are flirty, and how do you touch people you are flirting with?
