Aikido. Be yourself, and enjoy the time together, whatever it is that you are doing. Take her to botanical garden, road trip, dinner, rock climbing gym, drinking, anything - and enjoy those moments to the fullest, just like you would with a close friend. Once she gets to know just how nice and smart and fun guy you are, she'll feel comfortable, and even more importantly - curious. It doesn't take but a few days, and if it takes more than that, then she's a guilt- and fear-ridden freak who is not worth the effort anyway.
