Something that's not been hit on yet (and you probably know this, but I feel like it needs to be said just in case)…be aware of how much space she's comfortable with and careful with touch as well. The best first date I ever went on, the guy gave me a lot of space and didn't touch me until he hugged me at the end. That actually made me feel safe and I actually felt like I wanted to touch him at some point in the future (like holding hands or something). I don't know, there's just something extremely respectful about holding back physically at first. Of course, if she initiates touch, you may be in the clear, as that would show she probably doesn't have a problem with touch like I do (and other people do).

Also, I was nervous at first, but I quickly became comfortable (and I have pretty severe anxiety, so that's saying something), so don't worry about being nervous. I think everyone has some nerves at first anyway.

But anyway, good luck and have fun!

P.S. I'm so happy for you!
