Dunno who came up with No Nut November. Dunno why they didn't just cut out the middleman and call it Nutvember, since all you see is even more stuff designed to get you fapping. Almost like it was almost XXXmas. ...maybe that's the point.
It's kinda hilarious to me, since the previous iteration of "Don't Fap for a month to get something awesome" that wasn't in relation to NNN is a thread on /mlp/ where if you managed to complete the challenge, your waifu became real.
There was also a manga where the MC gets the Demon Queen sealed in their testicles, and the challenge was required to banish them for good, with succubi chasing them all throughout.
