Yeah, if I'd written anything particularly porny (which I really haven't, steamy is as far as I've gotten - I tend to be more of a drama/hurt-comfort/character piece/pure crack-fic kind of writer and reader) I wouldn't want the actors or other Powers That Be reading my fanfic, I'd be way too embarrassed! Some actors do though, I'm remembering one stating in a panel that in his opinion his character would be the fracker, not the frackee, so to speak, in the pairing mentioned.

I try really hard to keep my real identity and my fandom identity separate for many reasons, and that's one of them. I'm not sure how well I'd handle it if I found that an actor had read one of my fanfics, but at least them not knowing who I really am would spare me any embarassment if they didn't like it, and also spare me the same if they did like it, because I'd probably be all, eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!!!!! and a gibbering mess. :)

ETA: Which I should say there is one actor I've mentioned to that I write fanfic but that currently I'm attempting to concentrate more on my original writing, and currently I don't have anything out there that's for his show (am working on something off and on, but nothing ready for public consumption) and that actor does not know my fandom name, and so help me he won't find it out, at least not anytime soon! :)
