No Nut November, often abbreviated to NNN, is an annual 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. 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.

The rules of No Nut November are not set in stone, and participants tend to make their own rules. Some abstain from sex and masturbation completely, while others don’t deny themselves pleasure altogether and engage in edging. However, the most common rule is to avoid ejaculation for the entire month of November. Watching pornography and having boners are allowed, but participants cannot ejaculate in any way, shape, or form. If a participant has more than one wet dream, they are out of the challenge. If a participant passes the month with a total of 0 nuts, they are considered a victor and qualify for Destroy Dick December, which is a related internet challenge following No Nut November that encourages participants to take part in sexual activities such as intercourse and masturbation, after abstaining from them during the previous month.

While some participants claim that abstaining from ejaculating and not watching pornography has health benefits, there is no scientific evidence to support these claims. In fact, some medical experts warn against the challenge, as it can lead to pelvic floor dysfunction and other health problems. Therefore, it is up to individuals to decide whether or not they want to participate in No Nut November.
