Note: The terms "anal sex," "pegging," "anal play," and similar phrases in this guide refer to sexual activity involving the insertion of a penis or a sex toy into the anus. Sometimes, they may also broadly refer to other sexual activities involving the anus, including the insertion of a dildo, fingers, or other objects into the anus, or other forms of sexual stimulation to the anus to achieve pleasure.


Anal sex has been known since possibly the earliest records of human history, yet it's still widely misunderstood. To prevent these misunderstandings from spreading, this guide will provide a detailed overview of anal sex and all related topics to help you and your partner have a pleasant experience.

While anal sex may seem simple, it is actually much more complex than conventional intercourse and requires a lot of knowledge to ensure it is both safe and pleasurable. This guide will focus on the principles, safety, preparation, techniques, equipment, and advice to ensure you can perform anal sex correctly. While beginners may be tempted to skip certain parts, you are strongly encouraged to read the entire guide to get a comprehensive understanding of all aspects of anal sex.

Anal sex (and sexuality in general) is a field that sometimes lacks scientific evidence, making it difficult to draw rational conclusions due to insufficient evidence or arguments based on logical fallacies. While this guide will include some scientific facts, a large amount of the information comes from the experiences of various developers—methods that people have successfully used and shared, but that often lack scientific backing. At the same time, the sources of information may be subject to survivorship bias, making absolute truths difficult to ascertain. This guide will attempt to explain some methods and their potential effectiveness, but it is ultimately up to the reader to decide what to believe. This guide should be considered a compilation of various personal experiences, and the reader must use their own judgment on how to apply this information and consider any potential logical fallacies.
