Breaking the Chains of Masturbation Shame

When Dr. John Harvey Kellogg created his bland corn flakes in the late 1800s, his mission wasn't just breakfast-it was to eradicate masturbation, which he believed caused everything from pimples to tuberculosis. His tasteless cereal was designed to dampen adolescent libidos. While this anti-masturbation crusade might seem like an amusing historical footnote, it represents just one chapter in our complicated relationship with self-pleasure. As pioneering sex educator Betty Dodson observed, sexual progress isn't linear but rather "two orgasms forward, one orgasm back." The struggle between liberation and repression continues today, with modern wellness influencers unknowingly spreading 19th-century pseudoscience claiming masturbation causes brain damage and shrinks penises. What if everything we've been taught about this most natural human behavior has been filtered through centuries of shame, moral panic, and outright lies? For most of human history, people pleasured themselves without shame. Our primate relatives and countless animal species engage in self-stimulation, though humans uniquely continue to orgasm thanks to our cerebral cortex, which enables fantasy. Early civilizations viewed masturbation neutrally, even depicting it in art and mythology. The Greeks joked that Hermes taught his frustrated son Pan to masturbate when faced with unrequited love. Everything changed with the dawn of "modern masturbation" in the early eighteenth century when an anonymous London pamphlet titled "Onania" warned that self-pleasure led to fainting, melancholy, infertility, and death. The author claimed ejaculation essentially dehydrated men to the point of mummification-a claim that launched centuries of pseudoscientific fear.
