New relationship advice?

I just started a new relationship 3 weeks ago. So far we have been hanging out almost every day, but I just have some questions. What does it mean when I kiss her on the nose and she laughs? How do I know when we're ready to kiss (for the first time)? If anyone knows any of this, please help. Thanks.

she prob thought it was cute of you to kiss her on the nose. and if you've kissed her on the nose it's time go for the real thing.
