Naga Sadow frequently went into his masturbation sphere for hours or even days at a time. Sometimes his Sith adepts would knock on the door, saying, "Naga Sadow, what are you doing in there?" and Sadow would assure them he would be right out in just a minute and never mind those thumping noises. Using the masturbation sphere was a delicate process. One had to spend a great deal of time allowing the Dark Side energy to build, grow, rise, swell, expand, and only releasing the energy when the peak had been reached, or else the Sith Lord risked blowing his wad prematurely.
