I'm a science fiction writer and network engineer. I love technology so it often fits into what I write, usually tech that doesn't actually exist, but it will almost always be there to help accentuate a particular human characteristic.
My erotic works will be very descriptive and usually short. Although some of my longer works incorporate erotic scenes, they are there to add depth to a situation or character and will never be as in depth as my purely erotic works. It is too easy to have sex overshadow a plot line and deter from the story or development of a character.
