The best DATY I have had was from a guy who paid attention to my body language. If I made noise, he kept doing what worked. And its not just the clit that feels good. There are other areas of the cookie that are considered erogenous and pleasurable. So I would say experiment to see what she responds to best "body language and positive response" but its always good to start off light and work your way from there. Also, ask her what she likes and doesn't like to help get you off on the right foot.
