Well, I'd guessed that you were on some biological and as-far-as-my-parents-are-concerned level a girl (from your self-labeling as a lesbian but mostly from people calling you by your name), but figured otherwise you were in a gray area (most people respond to the "I don't know what gender you are!" comment with either "Oh, I'm a girl" or "Oh, I'm a boy").

On a related note, on the occasion that I'd mention you to my real-life friends (I'm not creepy, I swear, just sometimes I overshare), I'd usually flail for a bit about a pronoun and settle on using "ish", as in, "So I'm lj friends with this kid and ish just posted some gorgeous pictures of boys."
