Every form of technology humankind has invented has been co-opted for two uses: warfare and getting off. Electricity, internal combustion, the telephone, the Internet — there's no reason to think this trend will stop as we move into the future of nanotechnology, neuroscience, and space travel. However, whether the future is a Gernsbackian vision of flying cars and cloud cities, or a gritty gray cyberpunk world, there is always a need for sex.

Award-winning authors such as Joe Haldeman, Nalo Hopkinson, and Catherine Asaro are among the leading lights of science fiction and erotica who contribute to this book, as well as Paul DiFilippo, Sarah Micklem, Bruce Sterling, M. Christian, Thomas S. Roche, Saachi Green, and many others.
