About The Project

PSIgasm was conceived in 2010 by an HIV prevention specialist and an experimental physicist, both of whom moonlight as queer porn performers and are active in the Bay Area sex positive scene. The project revolves around measurement devices that can be used as sex toys, simultaneously getting people off and monitoring physiological responses correlated with arousal and orgasm. The first prototype was completed in January 2011, capable of recording and displaying the contractions of the pelvic floor muscles in real time. Since then the pace of work on the project and the interest it is drawing have grown exponentially. We are creating more complicated devices, building a web presence, teaching classes featuring the device, and collecting as much data as possible. All of the hardware and software is open source and the design is freely distributed, because we need as many people as possible investigating their bodies.
