It could be emotional, unlike men most women need some sort of emotional input to sex, pure technique rarely does it.
I could do with more background info but if she is a GF or you regularly meet her, go on a date, a date date. Somewhere nice as well so she can get all dressed up and build some romance, or you could cook for her, just make her feel special and connect with her and it should fall into place.
Also, and this was a huge sticking point for me for so f***ing long you wouldn't believe it, is to use your mouth. And not just for business either - use it to communicate arousal/affection/whatever. And this goes for anyone: don't be a mute in bed. You don't have to be loud (in fact that's probably left for her to do) but making no noise whatsoever is kinda unnerving.
