The Myth Of Magnum Condoms

Size matters, but not in the way you think

- Dr. Megan Stubbs

You know what they say about guys who have big feet, right? They wear condoms that fit their cocks. No, people aren’t saying that.

“If the shoe fits, wear it!” You’re probably more familiar with that one. Can you imagine if you bought shoes two sizes too big in order to impress someone? That would be silly, not to mention a tripping hazard. So why buy condoms that don’t fit your penis? I have a pretty good idea where the “bigger penis equals better sex” fallacy came from—porn—but I won’t hold them solely responsible. The idea also stems directly from a lack of proper sex education. Penis diversity is never talked about—let alone different sizes of condoms.

But before we get into that, let’s talk about penis size.

A meta-analysis published in the British Journal of Urology International found that, globally, the average erect penis length is a little more than five inches—a bit shorter than the iPhone 6s. There are outliers, of course, but if we surveyed 100 penis owners, only about 15 would have penises longer than six inches and only five would have penises shorter than four inches. The average penis girth found in the study was 4.6 inches. With the magic of pi, we know that means an average of about 1.5 inches in diameter.
