Going on my first Bisexual Date With A Girl.

I am a female, and this Girl is coming up to see me on Sunday. I really like her, she's the first girl i've ever been attracted to. I am SO SO nervous about interacting with her on a romantic level. I know that she likes me too but I feel so intimidated by her experience as a gay girl. I'm nervous about how to act and what to do. I really do like her a lot.
