"No Nut November" is an internet challenge of male sexual abstinence during the month of November. It originated in 2011 and grew in popularity on social media during and after 2017. The challenge requires men to go thirty days without ejaculating, whether its with a partner or on their own. The challenge is a month-long affair, hence the name. Although No Nut November was originally intended to be satirical, some participants claim that abstaining from ejaculating and not watching pornography has health benefits. The challenge is associated with the NoFap community on Reddit, which encourages its members not to masturbate.
