There was a scientific study on this. Apparently not cumming for the first 6 days steadily increases your testosterone and sexual drive but after the 7th the body resets.

But then again some foods alter the levels, lifestyle, beer, etc.. Even being in threesomes makes your body kick up the testosterone levels a notch as subconsciously humans "rise up to the task"

So best to just enjoy whatever rhythm works for you.

If I went that long I'd struggle to read a book and would drop innuendos in every conversation I hard.. It would be pretty Hard! (tu dum!)
