Honestly, my first date was SUPER awkward.

I was 15, he was 16, and we went to see this play at my school called Joan of Arc was sooooo incredibly dark and boring (obviously, it was Joan of Arc). Halfway through, he awkwardly grabbed my hand and I was like "Auuuugh!"
Okay, so that's probably not what you were looking for. But I'm telling you that to a) give you advice and b) some hope. A) Try not to build up too much expectation about a first date: more often than not, because both of you are probably nervous, it will be a little awkward and not the magical idea you have in your mind. That's okay! Just relax and have fun, and try not to take yourselves too seriously.

B) This particular boy and I ended up dating for 8 more months after that really awkward date (I know, not long, but forever when you're 15) and we had a great time. 22 years later, he's married with two children, I live 12 hours away, and we're still friends who talk from time to time, I think mainly because we had that connection of being the "first." That, and after hating each other for 6 months, he became one of my closest (platonic) friends during high school.
Anyway. Have fun, and good luck!
