Good blog, good story...
I can't wait to hear how it turns out. Good luck! and try not to worry about it. All of these little life experiences are valuable, regardless of whether or not they turn out as we hope. The more guys you ask out, the more likely you are to find someone right.
I probably wouldn't be with my boyfriend of 2+ years if I hadn't fessed up and told him "I have a crush on you." It took a few weeks for me build of up the courage (and make sure he was available), and I've never regretted it since!
