The South Park guys made a bizarre movie about a device like this (which was a beam weapon), "Orgazmo". Possibly one of the weirdest movies of the 90's which was worth watching.
The dark side of it was that it could be so intense, “perfect pleasure”, as to ruin someone’s life as they tried to achieve it again.
Similarly the “drug” of choice were “wire heads” who had a wire connected to their pleasure center. Abuse of which led folks to just plug in and starve to death. But it was not as intense as the tasp.
