No Nut November

No Nut November is an internet challenge revolving around abstinence from masturbation, sex and ejaculation (or colloquially "to nut") during the month of November. It originated in late 2010 and grew in popularity on social media during and after 2017.

History
Although No Nut November was originally intended to be satirical, some participants say that abstaining from ejaculating and watching pornography has health benefits. An Urban Dictionary entry for No Nut November was published in 2011, and, in 2017, the movement started to gain popularity on social media. It is associated with the NoFap community on Reddit, which encourages its members not to masturbate. The Reddit community /r/NoNutNovember grew from 16,500 subscribers in November 2018 to 52,000 subscribers in November 2019.
