Hi there, only just saw this thread today.
Depends on the story, but I think I prefer to write in the first person for stories that are set in one scene.... but if it's a story that evolves over a period of time, where the two characters are apart from each other, I think the third person is better. One thing I have used is multiple "I"'s in a story, so I could really get in the mind of two characters. Maybe that's just laziness!
Having said all that, I think I usually prefer to read stories that are in the third person.
The one we've not mentioned is stories in the second person ("You take off your dress and feel a shiver run down your spine as you see the dildo you're going to slide into yourself...") but the less said about them, the better. Shame, as they sometimes have the best ideas, but are just hard to read. I mean, I've never felt a shiver run down my spine for that reason.
As for how I write, I use Word almost exclusively, right from the start. I'll usually start with a thought of a good mental image, or a fancy turn of phrase, something profound like "... it was agony to crawl towards him, knowing that he would beat her with the cane she held in her mouth, but she chose this life, and she could not have been wetter." And then I'll work out plot-points and characters that can get me to that point in the most realistic and entertaining way.
I know you're supposed to start with the characters and work from there, but hey, who's got time for that?!
The method I described was something that Douglas Adams confessed to - he really wanted the line "And so, Ford and Arthur were chasing a Chesterfield sofa around Lord's cricket ground, when the West Indes only needed 23 runs to win." to be in his book, so moulded the first four chapters JUST to get to that line!
Umm hope none of that sounded pretentious. Keep writing all, and good luck to each of you smut-peddling, filthy minded bastards!
