In my 23 years I have been in many long distance relationships.
Some were of the puppy love variety. A girl I met a camp became a pen pal girlfriend. A boy I met online, who happened to live across town, became a long distance boyfriend when we stayed out too late one night and he lost his driving privileges.
Since college, my long distance relationships have taken on a more traditional form. Two people are together in one place, one person moves, and then BAM, you're in a long distance relationship!
Except there's not a whole lot that's "traditional" about the way we meet, make friends, communicate and keep in touch these days. And I'm thinking that all of this change affects the queer community a little bit more.
