I don't really agree with that because girls love to be touched, especially by pretty/sexy men. If a girl likes or loves you, and you touch her..., it will show her that you might be interested to sleep or date her in the future.
Of course, girls don't like easy guys so you gotta neg her or laugh at her a little, you never gotta be taken for granted...because they love challenge, if it's too easy they'll run away. Girls are shy and scared to touch us most of the time, so it's our job to do this in order to make them feel better with us and to reduce their level of shyness. At first sigh, the more pretty you are, normally... the more they wanna be touched.
Let's think the other way, we love to be touched by sexy/pretty women? Right? Why wouldn't they like the same scenario with us too? You just gotta game more with women because you gotta sell your salad and be different from all the other bunch of boring men's who just wanna fuck and have nothing to say.
Therefore, I conclude that touching is a MUST DO!
I don't know if I answered your question but please give feedback!
