I already know why and how people do it (I'm a hands on learner muhahah get it? sorry) and I get that the stims make it possible to focus psychologically on beating your meat like it owes you....stims, for hours without getting bored, but what I'm asking is what mechanism of stims makes it so you physically gain the sudden super power to be able to decide to nut seemingly at any time you choose between now and The Rapture. which seems like magic compared to my unstimmed little bastard cave explorer who is an undefeated and undisputed 3 pump champion when there's a copilot operating my joystick, and taps out at 2 videos when I'm in manual operation on a solo mission.

Is it a nervous system or maybe a neurotransmitter thing? Is it actually just a psychological thing, allowing you to tap into your inner degenerate, transcending you into the David Goggins of worm slapping, embarking on a neurodegenerative journey of finding the "perfect video"?
