An experiment begins with the explanation: “To ensure accurate results, please don’t hold back your voice, urine, or orgasms.” Soon, the vagina goes numb and loses the sensation to hold back urination… This record documents the experiment involving two SOD sex science lab researchers and six SOD female employees undergoing individual fixed vibrator stimulation (over clothes, directly on the genitals, and in various positions), culminating in a simultaneous six-woman experiment.
