no nut November HARD MODE 

This is a twist on the no-nut November challenge, only meant for true gods, only for the most manly of men.

You can't nut for a WHOLE year, from January 1st all the way to December 31st.

There are very few men who have completed this mountain of a challenge, and those who did, have transcended being mere mortals but have became GODS.

"only 5 days away from completing no nut November hard mode! I cant believe it "
