You really need to slow down and listen to what she says vs what she needs.
This isn't about being 'vulnerable', it's about being a leader, pushing her attraction buttons, making her anticipate intimacy.
Being a man. I have found two things that helped me understand that what we think women want is not what they really want.

two things I have learned much from was "The way of the superior man" book, and writings of David Cunningham. google "david cunningham marriage"
