New technologies generate new experiences. Kenneth Maxwell, a professor emeritus of biology at California State University at Long Beach, predicts that psychologists, chemists, pharmacologists, and computer programmers will collaborate to supplement the sensations that produce sexual pleasure. We've already seen how technology provides vastly increased visual stimulation, and Maxwell thinks all our other senses are similarly ripe for enhancement. "Sensations still untapped electronically are odors, tastes, touch, pressure, and kinaesthetic sensations," he writes. "In the case of odors, we can expect that research will unravel the presently unsolved mystery of human sex pheromones." Other researchers are exploring a "sex chip" that intensifies desire by sending shocks to relevant regions of the brain.
