i bet it's 8-12 hours, i've done a few of those and always feel guilty at the end because i wasted the whole day just fapping, my bepis hurts, i stink and smell bad and feel greasy and awful and all I did was fap like 6-7 times till it hurts, you can't even do anything else because the brainfog clouds your judgement and i start sounding like a moron because i feel and speak more sluggish, the friction burns come the next day it's pretty awful all around, i could have stopped at 2-3, its never worth it
