If only it was about time. if only!
No, "time" is a rookie and logical assumption. What it's really about is the "man energy" in your balls, so the more you wank, the less "man energy" you have for other tasks, especially that of finding and harassing desired sexual partners in real life.
By "holding it all in" you become super alpha sigma male capable of succeeding in any and all tasks you desire, because the ball energy goes to the brain or some shit. It's just kinda coincidental that the tasks these guys seem most interested in is talking about their balls and semen all the damn time, like a poorly disguised coping mechanism for horniness.
