First TV show I had self-insertion fantasies about:
Star Trek: TNG. I had this brilliant character who had superpowers due to a poisoning in a war...it was wicked cool.
First fandom in which I interacted (online and in person) with other fans:
Supernatural, before that I was a lurking lurker who lurked.
Pairing in the first slash fanfiction I read:
Fraser/RayV, way back before there ever was a RayK.
First RPS/RPF I read:
It had to be SPN. I think I was aware of the genre before, but I wouldn't touch it with a ten-foot pole until the Supernatural fandom corrupted me.
First fanfiction I read that made me think, 'YES, this is exactly the kind of fanfiction I'd like to write...':
Is it weird that I don't ever remember thinking that? I don't even remember what the first fics I read in the SPN fandom were. Actually, wait, scratch that...back before I was into SPN, I used to read Naruto fanfic (don't judge me!) and there was this GORGEOUS Kakashi/Iruka fic on FF.net...and I wanted to write like that. I don't even remember what it was called now or what exactly the plot was, but it was beautiful.
Pairing in the first fanfiction I wrote:
Uh, well, before I ever wrote anything I considered "fanfiction", I wrote a story for my friend's birthday that had the pairing Friend/Kakashi...I'm not sure that counts, but my friend was madly in love with Kakashi, so naturally I wrote her a story where he seduces her. I guess besides that...well, there's a reason I post my smutty stories on anonymous memes, I am unwilling to publicly admit to the pairings.
I think back before I was even consciously aware I was doing it, my OTP was Data/Geordi. From then on it was every single obviously slash OTP in every single thing I watched...up until SPN, where I suddenly couldn't get over the whole incest thing (or angel thing) and then my OTP became Dean/Books and Sam/AngryFace.
First RPS/F OTP:
Uh, this ones kind of weird to answer, because I only read AUs and I don't connect the characters with the actual people...so...yeah...I guess I'll say J2, since I don't like Misha fics...and so far Supernatural is the best fandom for AU RPS fics that I've found (not that I've gone looking.)
First fannish friend I met in person:
First character I formally roleplayed:
I've never roleplayed a non-original character.
(I am so amazingly exhausted, but I want to wait until my sister and her boyfriend get home before I go to sleep...this is probably ridiculous of me. It's not even 9pm...)
