I don't usually do this, but it looks kind of fun . . .
First TV show I had self-insertion fantasies about:
Bonanza -- if it counts that I used to fantasize myself as Little Joe Cartwright. First time I self-inserted as my own original character was Gunsmoke -- in the Burt Reynolds years.
First fandom in which I interacted (online and in person) with other fans:
Star Wars, back in 1979, first in newsletter 'zines and later as a fanfiction writer. Later, I wrote Indiana Jones fanfiction too.
Pairing in the first slash fanfiction I read:
Kirk/Spock, although the story I read was a satire of the K/S genre, done for laughs. First serious slash I read was by Bone Fauna, and I think the pairing was Legolas and the Twins.
Pairing in the first fanfiction I wrote:
Han Solo and Princess Leia, implied. And it was a romantic pairing, since any graphic sexual activity was forbidden.
First RPS/RPF I read:
Oh, good lord. I really don't know, since I don't read RPS. I think it was Orlando Bloom/Sean Bean with some H/C from Viggo. But let me put in a good word for a hilarious piece of 'fanfiction' called Shorts Weather, which featured Stephen Colbert and Bill O'Reilly in a hotel room with some slashy overtones.
First fanfiction I read that made me think, YES, this is exactly the kind of fanfiction I'd like to write.
Elise LeRouret's Pottymouth. It was so original, so different that it made me see the possibilities in Tolkien fanfiction. I had previously thought, why bother? The story has already been written. Oh hell no it hasn't!
Indiana Jones/Marion Ravenwood. And let me tell you, I'm pleased as punch that I turned out to be right, even if it wasn't the way I would have hoped.
First RPS/RPF OTP: None
First fannish friend I met in person:
A wonderful woman named Bebe, who has been my penpal since 1983, when she illustrated one of my Star Wars fanfics. We've met many times in real life.
First character I formally roleplayed:
