I was about 12 and his name was Steven. He was 14 and I didn't realize I had a crush on him until he moved. I cried myself to sleep that night, but he only moved about 20 blocks away.
I know you asked for the first, but I'm just going to tell you all of them.
My second crush would be this phenomenal girl named Dori. I met her while transferring to another school. She was 14, I was 13. We had so much in common (while I don't really believe in soul mates) it felt like it was meant to be. I haven't seen her since 2004. I miss her so much.
My third crush was my best friend. I wasn't interested in him in that whatsoever. I spent the whole summer of '09 with him and things changed. I got over him by summer 2011. Now he's just the goofy brother I never had.
My fourth crush is a bastard that I met at college. We spent an entire semester hanging out. The semester ended, July came, and poof. I confronted him last Thursday. It was the first time I saw him since May 2012. Well, I actually saw him the Tuesday before but didn't say anything. Anyway, he tried to explain why he did it, but I guess I'll find out more on tomorrow.... I hope...
