Coquetting is a psychological technique Stirling Cooper teaches involving strategic push-pull dynamics to create intense desire and maintain control in sexual interactions.

Critics argue these methods shouldn't be taught to average men, though Cooper counters that these same women perform these acts on camera. The sensational title draws accusations of clickbait, with reviewers noting the "penis growth" claims overshadow the book's legitimate relationship and performance advice. Some critics also question whether permanent enlargement is possible or if results are temporary enhancement effects.
