Quoted By:
Shinji had been having trouble with his sync rates with Eva 01. And did he ever regret opening his mouth when he told Dr. Ritsuko he had been masturbating lately as a possible reason for the difficulty.
Even after Shinji was fitted and locked with a medical grade Nerv issue chastity device, his sync rates were still below par. Shinji kept reporting that he had stopped masturbating, and Ms. Katsuragi reported that she hadn't overheard Shinji whacking it in his room either. She was sure he couldn't possibly be pleasuring himself because she kept the key with her at all times.
She had noticed Shinji'd been spending more time with Kaworu at his apartment, but figured he was just burning off steam playing videogames with his friend, like he said he was.
Still, sync rate results continued to be below expectation. Dr. Katsuragi decided she wanted to have Shinji stay in chastity for another week or two to see if continued abstinence would improve his sync rates.
"A week or two, or as long as it will take really to rule out masturbation conclusively as the source of your problem" Shinji felt himself getting weak in the knees
