Robots, VR and the future of male masturbators

There were pillows, mattresses, bottles, a couple of cuts of raw meat and even a vacuum.

When I was a kid, masturbation was an adventure in engineering. As I've come of age, however, so has the sex-toy market. After centuries of ejaculating into whatever we can find, a seemingly robust market has sprouted up around male-masturbation aids.
