It helps if you know more about her. This might sound a little cold-hearted, but learn to pick up on her insecurities whenever you can and lightly poke at them in a humorous way.
For instance, one of my plates right now happens to be a little naive due to her strict upbringing. She's also pretty inexperienced and weighs in at a mere 100lbs, so I constantly call her a "good little girl" and tease her about what a cheap date she is. This conveniently gives me all sorts of leverage to challenge her to break out of her comfort zone and prove me wrong.
The third night we were together she predictably went down on me like a true champion. After about five hours of raw, sweaty sex, she looked up at me with an evil grin and whispered in my ear "So, do you still think I'm a good little girl?" My response was something along the lines of "Yes, but you're learning well.

" and then I kissed her.
The idea is to keep raising your value through subtle ****y humor so that she develops a perpetual desire to prove herself to you, and simultaneously reinforce a convenient justification for her to act on her sexual urges with affection. Here's a secret: Most experienced PUA's will tell you that attention is currency, encouraging you to withdraw it if she misbehaves. This really is only an incomplete picture.
The true currency is not only your attention, but your
affection. When a girl associates your affection with sexual intimacy, it builds
emotional equity and she will start to align the concept of "love" with your presence, fantasizing about you when you're gone. Your goal is to seduce her. You want her to completely fall for the soulmate myth while you remain firmly planted in reality.
