I first realized I was gay when I was 13, and I had a "girlfriend". I was only 11 when we first started "dating", too young to understand relationships at all, and the only reason I became her boyfriend was because we were best friends and I pestered her until she told me what boy she liked. And I thought to myself "wow, a girl likes me, so I guess I have a girlfriend!"
Instead of saying "I love you", we used a secret code word; Chicken. Yes, Chicken. We would spend hours talking on the phone about whatever 11 and 12 year old kids talk about on the phone, and we'd just randomly drop the word chicken in the middle of our conversations.
As we continued this relationship more often she would cuddle with me and stuff, and I did NOT like it. It always made me feel so uncomfortable. All my family thought it was so adorable that I had a little girlfriend when i was that young so they kind of kept pushing me with it. Even though we were "dating" for 2 years we never kissed. We talked a little about sexuality, mostly because she liked anime and started reading fan fiction, and most of what she read was hypothetical relationships between male anime characters. When she talked about that stuff it made me curious, so after that I'd look up gay porn all the time... first I said "I guess Im bisexual because I have a girlfriend," and after that I considered the idea of being gay and how it sounded great... and then I considered the idea of being straight and how vagina sounded icky!
So one night on aim I IMed her to come out to her, the first person I'd ever come out to. it went something like this;
me:hey
she:hey
she:chicken
me:I have something important to tell you, ive been meaning to tell you for a while
she: oh, okay
me:well I think im gay...
me:and if theres any part of me thats still straight it's slowly dying inside of me
she: oh okay : )
and after that we talked on the phone and that went something like this;
she: you're gay.
me: yea, I know

she: you're gay.

me: yea, I know

she: you're gay.

me: yea, I know

she: you're gay.

me: yea, I know... it's not a big deal.
we remained good friends after that, and she came out to me as a lesbian maybe a month later. We were friends for maybe 5 or 6 years, then we kind of drifted off around 15 or 16 years old because we went to different high schools, had different sets of friends, and our interests totally diverged. Now we just talk a little bit online here and there.... I think she's had 2 or 3 girlfriends in that time period and currently has a boyfriend, and lucky me has only had the chance to flirt with a guy once ever!

I'm planning on changing that quickly when I start going to NYU this fall! Other than that, coming out to people went well enough not to make them interesting events at all, which is a good thing.
Every once in a blue moon I think about that weird "relationship" and think "wow, that was incredibly stupid! Kids do such stupid things." And just few months ago, my mom asked me for the first time; "when you talked to amanda on the phone as a kid, why didn't you say anything besides the word chicken?"
