Mass debating is the way Chris pronounces "masturbating".
|“||actually figured it out for myself, in my room one night after having unlocked the parental lock; I found the pool scene in "I Like to Play Games Too", and I just figured it out for myself.||”|
When he first started mass debating, he did so by lying face down on his bed (also known as prone masturbation) and rubbing his duck with a washcloth. In early 2009 he would sit on the bathroom washbasin during the act. In Ivy's Q&A it was mentioned that Chris has used his pillow, folded in half, as a masturbation tool.

While it is assumed by many that Chris has a voracious sex drive and spends every day whacking it, the truth is quite different. Possible factors for this include the fact that he has a bent duck which would most likely make masturbation painful, and he probably struggles to get/maintain an erection owing to his obesity and general poor health. The sex audio with Julie seems to indicate that it takes Chris around 20 minutes to orgasm, which means that masturbation for Chris must be physically exhausting. Chris also believes that he has a limited sperm count which may have him limit his sexual activity. Also, Chris was at one point prescribed the antidepressant paroxetine (Paxil), which (from what was heard from him) caused some sort of sexual side effect, perhaps slowing down his ability to orgasm.
In January 2018, Chris claimed that he no longer masturbates. While Christorians had speculated that this could have been the result of his oestrogen treatment, which is known to decrease libido in men, he told Miss Cherry in a conversation on Christmas 2019 that he had given up self-abuse as early as 2011, back when he had first described himself as a tomgirl but limited his activities to cross-dressing.
On 18 November 2018, Chris's Twitter uploaded a video of himself mass debating his flaccid duck while singing the song All-Star by Smash Mouth. Chris is noticeably stressed and uncomfortable during the act. It was later found that Chris was manipulated into filming the video by the Idea Guys. The video was posted onto Chris's Twitter either by the Idea Guys, or by Lillie of the Teen Troon Squad, using the Idea Guys as a red herring.
