I have lots of stories about this. One time I was walking home with my (girl) best friend in middle school and she told me I was the only boy in the school no girl had a crush on. I asked why, and she explained it was because I was thin, pale, soft, shy, withdrawn and had glasses and was always reading. I got sad and asked what I was going to do and she started telling me about several boys in our grade who had crushes on me. I was like "I had no idea they liked boys though" and she was like "neither do they, but they will pretty soon." It was the beginning of me realizing I was queer.
