If you cum enough everyday and drink all the cum then you shouldn't ever need to eat because the cum should have enough food molecules for survival, I think. If your balls are big enough you should even be able to feed your entire family with nothing but your cum. However, as the age-old saying goes, don't try to have a family bigger than your family jewels can feed or someone will starve. Your pregnant wife and/or daughter's breast milk can be used as a substitute for cum but beware that it dries up a few years after the pregnancy ends, so don't make the fool's mistake of getting trapped in an unending cycle of needing to continuously impregnate your daughters to keep their milk flowing to feed everyone, as that will just keep expanding the family and exacerbating the problem. Most importantly, remember that cum can only be fed to girls because feeding it to boys is gay which is a mortal sin.
