LOL!! I see where you're coming from bt_author.
I write a lot of really nasty horror. I can happily think up the most gruesome acts, create nasty monsters and beasts, and write about generally horrible things. I've even had to go to bed once or twice and sleep with the lights ON because what I've written scared me!! (that's a really sad confession)
Just because I'm capable of thinking them up doesn't mean I'll ever be physically be able to do any of them. I'm actually quite patient, boring and normal in person. I'm a banker, for goodness sake! How exciting could I really be if I'm excited by numbers and banking stuff??
How did I get into writing horror?
Easy answer. I worked in a male-dominated industry. There were 28 males in the office. And me. My boss treated me like the tea lady instead of a fully qualified banker. I got frustrated one night after work and wrote a nasty little horror story about him being mutilated in several different inventive ways. I posted the story to a magazine. They published it. I pinned the clipping to his door. He thought it was hilarious. It didn't stop him from being a chauvinistic pig, so I wrote more, getting more inventive, more gruesome, more violent. I pinned all the clippings to his door. It gave me encouragement and incentive to create new characters and new situations.
They're just stories. I write them because I enjoy writing. I enjoy trying to fool the reader into thinking they know what's going to happen next - and then shocking them with an unexpected twist.
I've branched out since then and write dark sci-fi or dark fantasy as well because the challenge of creating whole new worlds in which to play fascinates me.
Just as many people read for entertainment, I write for entertainment. I enjoy horror films and books for fun, so why not create something in the genre that gives me so much pleasure?
I say if you're enjoying writing and you know that most of it is just venting frustrations, then I say that's healthy. Let's face it - if you're venting your frustrations on paper, then you're WAY less tempted to go out and really do it!
