My favorite genre to write is fantasy, and I like just about any kind of fantasy - dark/goth, comedy, epic, classic, fairy tale, modern, and of course, mixing it with any other genre like sci-fi, thriller, mystery, etc. I've also dabbled in non-fiction and poetry, but I'm such a fantasy geek. Oh! And I love crossovers! Under my fanfiction.net account, DragonStarbo, you'll see that most of my recently updated fics are crossovers. I also enjoy a bit of hurt/comfort but unless I’m really in the mood, I prefer things to have a balance.
I can play both Dean and Sam, but I'm better at Sam, in my opinion. When it comes to writing love/sex scenes, I prefer romance and closeness and fluffiness, but I'm not afraid to get graphic. I just have a very limited comfort zone of fetishes - basically, gags, blindfolds, and binding (nothing too harmful). I draw the line at whips and blood and tentacle porn. (I should say that I don't condemn anyone who's more into this stuff than me.) I’ll be honest and say I don’t know all of my boundaries or how far I’ll go in a fic/co-write/rp. It really depends on the writing and those involved, I guess.
