I would increase the amount I wank every single day leading up to that point, pushing my limit, trying to get PBs. I’d hire scientists to figure out what helps with the production of testosterone, semen and other bodily elements that contribute to increased horniness and sex drive, and then use those findings on the day —> e.g eats tons of oysters as an aphrodisiac and so on) I’d invest in the most expensive highest quality lube possible, the most extravagant and high tech porn set up (dual monitors ultra high definition and clarity etc), and also have a bag of drugs that’d help me with the motivation and dopamine needed to beat the fuck out of my meat even when I don’t want to - weed, adderal, cocaine etc
