As you move through the levels of the second stage , if possible, let her take the lead toward becoming more intimate. If she initiates deeper levels, you will know that this is what she truly desires, and it will allow her to feel more in control of the situation. If she feels in charge she's less likely to become afraid of more intensity.
If she is shy, you can still help her feel in control by inviting her rather than taking her down the path of Cyber-Seduction. Ask her: Tell me about what you're wearing? This is better than asking her, What are you wearing? (if you haven't reached this level of intimacy yet.)
