It is pretty hard to narrow down my first love. Seriously--I was the girl who was ALWAYS crushing on (multiple) guys. I remember having a couple of crushes before I started kindergarten!
There were the small, ongoing crushes--my handsome older cousins (and let me tell you, I am not the only person who thought those guys were extraordinarily good looking, or who had crushes on them!)--some of the guys in my class at school (*sigh* Dwight, *sigh* Jared...), etc.
There were big, painful teenage crushes. 'Nuff said.
I had some dear friend-guys and a couple of "almost boyfriends" in college. However, I really did marry my first true love.
