You probably were able to build attraction with her, and I agree with the previous post, you moved too quickly.
I am a firm believer in taking a girl multiple places before the seduction location. It creates the illusion that she has known you longer. Typically, two or three places is enough for me. I like to take a girl out to dinner, then for a walk. Walks are great dates. Then at the end of the walk, she will be back at your place
You need to build comfort with her on the dates. Ask her questions about her childhood, her future, whether she is adventurous, and those types of things. The key is to avoid small talk, and actually get to know her.
When I do these things correctly, I almost always close the deal.
Another hint: when you are touching the intimate places of her body for the first time, just slide your hands over her, that way she can't remove them. Slide over them a couple times, and she will want you to do more.
