Whether whispered in locker rooms or searched late at night, penis size has been a lifelong curiosity for men. And while the internet is full of myths and ego-driven claims, real science tells a very different—and much more fascinating—story. At supremepenis.com, we reveal 15 of the most surprising, funny, and useful curiosities about penis size you probably never heard before.
1. The Average Erect Penis Size is Smaller Than You Think
According to a 2023 global meta-analysis published in the British Journal of Urology, the average erect penis measures 5.16 inches (13.12 cm) in length. Flaccid? About 3.6 inches.
2. Size Has Nothing to Do with Shoe Size
Despite popular myths, no scientific correlation has ever been found between shoe size and penis length. It’s just that—a myth.
3. Growers vs. Showers is a Real Thing
Some men have small flaccid size that grows significantly when erect (“growers”), while others remain about the same size (“showers”). One study found that around 70% of men are growers.
4. Penises Can Shrink Temporarily
Cold temperatures, stress, or fatigue can cause temporary penis shrinkage due to blood vessel constriction. It’s completely normal and reversible.
5. The Penis Stops Growing After Puberty
Most penile growth occurs during puberty and stops around age 18–21. Despite claims online, natural growth after that age is rare without external intervention.
6. The World’s Longest Medically Verified Penis
The record for longest medically verified penis belongs to Jonah Falcon, who measures 13.5 inches (34.3 cm) erect. But don’t get obsessed—he’s an extreme outlier.
7. Penis Size Has No Correlation with Pleasure
Women consistently report that size is far less important than technique, emotional connection, and confidence. Most nerve endings are located within the first 2–3 inches of the vaginal canal.
8. Testosterone Doesn’t Equal Size
High testosterone during puberty influences genital development—but higher testosterone in adulthood doesn’t increase size. It may, however, impact erection quality.
9. Penile Size Varies by Region
Studies show slight regional differences. Countries like Ecuador, Congo, and Ghana report higher averages. But variation within each country is much wider than between them.
10. There Are Different Types of Penile Shape
Some men have upward curves, some downward, some perfectly straight. Some penises are wider at the base or head. All are normal.
11. Porn Has Distorted Perceptions
Most male porn actors are selected for large size, leading viewers to believe 7–10 inches is “normal.” This creates a false sense of inadequacy among men and skewed expectations among partners.
12. Penis Enlargement Surgery Exists—but It’s Risky
Surgeries to increase penis size do exist but often come with serious risks like nerve damage, scarring, and dysfunction. Natural methods are safer and should always be the first step.
13. Fat Pad Hides Size
Excess body fat around the pubic area can hide up to 1 inch of visible penis length. Losing weight can make your penis appear larger—instantly.
14. Penile Size and Race: Myth or Fact?
While some differences exist in averages across ethnicities, they are minor and not biologically significant. Variation within any race is greater than variation between them.
15. Confidence Trumps Size Every Time
Ultimately, what matters most isn’t what you’re packing—it’s how you use it. Confidence, communication, and connection matter more than inches. Every man can learn to satisfy and lead, regardless of his stats.
