The rules of No Nut November (according to quick Google):
"You cannot have sex, masturbate, or nut in any way, shape or form
Watching pornography and having boners are allowed, but you can’t nut
You are only allowed one wet dream.
If you have more than one, then consider yourself out.
You do not have 3 strikes; you only have one shot at it. If you miss it, you’re out.
If you have passed the month with a total of 0 nuts, you are a victor and you shall qualify for Destroy Dick December (Not Recommended)
Look, man, just don’t nut in 30 days"
Even without the first rule it's a singleplayer game for me so I'd be shit out of luck regardless but co-op is also right out, it seems.
