Listen mate. When I'm talking to a girl I just put my hand on her arm. Like they do to us. I leave it there for a minute and I take it away.
There's two routes here. One, it looked like she enjoyed it. So I take my hand away whenever she does/says something that I dislike. I'll turn a little too, like I'm going to walk away. When she does something I like again, I'll put my arm back and turn into her. I'll touch her more places as her attraction increases. Touching her where she enjoyed it the most, or what I made symbolize greatest pleasure right before I leave. Or start undressing her. Depends on what hour it is
The other route is less favourable. Perhaps she did not enjoy being touched. I'll still continue to do it two or three more times. Watching to make sure she gets more comfortable with me touching her. It also let's her know that I'm not dangerous. This one could just be afraid, who knows what's happened to her in the past. You have to show a woman you know how to touch her. If I play my game right it should help her to open up as I build her attraction.
