Perhaps this is because I turn off all outside influences and go to my own little corner of my house, or perhaps it has something to do with the fact that I'm alone with myself. Maybe it has something to do with my skin breathing, or the sensations of my fingers running along my skin when i'm caught in the muck of writing that hits us all sometimes.
Whatever it is I come to focus, I center.
Especially as an erotic author I find this process exhilarating. When I write fantasy I like to handle things, whether its swords, or fabric, I like to enter a specific state of mind, and I'm discovering I am that way with Erotica, too. Sometimes listening to music will help, but always it helps to strip off the jeans and t-shirt, kick off the undies and yank that restricting bra off and simply Write Naked.
