your not dumb just head to the monster town its the second town in the game and go into the pub there and goto the toilet there and you will get 2 prompt choices goto the back of the toilets and use the glory hole so patrons of the pub fuck your mouth and load you up on food (cum) this will take a while but its an easy way to get your food counter to go up.
hope this helps.
ps if you need help on anything else just message me and ill do my best to share my knowlage from my gameplay over the past year of playing this game also there is a wiki of this game that does help on most things about the game but wiki isnt always as acurate as it makes out.
