My slash fan fiction writing. My offline friends - save Ro - just know that I write fan fiction, not that it is graphic slash. I find I like it that way too because I don't have to try and explain why I like slash, why I like writing slash, and why I like spending so much time online with other writers/readers of fan fiction.
Most of my online friends are readers/writers of fan fiction and that's something we all share a passion for. I have no offline friends I see daily/weekly/monthly who are writers and it's nice to have friends who understand where I'm coming from with my writing and have no fear of giving me honest feedback. (at least I hope so)
