Whether you've seen two penises in porn or 50, it's probably become apparent that they come in all kinds of shapes and sizes—in both length and girth.
And while you know that size doesn't really matter, you can't help but wonder: What size is, well, average?
Turns out there may be an answer to your curiosities, as some researchers have taken the time to explore the length and girth (a.k.a the circumference, or entire length around) of the average male penis, because, why not?
One of the latest large-scale studies took place in 2013, when Dr. Debby Hebernick, a sex researcher and educator at Indiana University authored Erect Penile Length and Circumference Dimensions of 1,661 Sexually Active Men in the United States.
As the name suggests, she gathered self-reported data from 1,661 men (and incentivised them to do so accurately by offering to match them with a better-fitting condom). From her research, Hebernick found that the average penis length was 5.7 inches, and the average girth was 4.81 inches when erect.
She also found that the means by which a man gets erect may influence his size. Specifically, she discovered that men who were aroused via oral seemed to get bigger than with manual stimulation. (Good to know?)
Another paper published in BJU International compiled research from 17 studies that measured the penises of a combined 15,521 men. The men were all measured by health professionals using the same standard procedure to ensure the numbers were as accurate as possible. And they looked at both erect and flaccid penises.
From their findings, the average flaccid girth, was 3.67 inches. Erect penises averaged 4.59 inches around. For some size reference, that's about the width of a tube of toothpaste.
There are some caveats, though. Mainly, these studies didn’t control for things like temperature, level of arousal, and previous ejaculation.
Still, whether a penis is the size of a tube of toothpaste or not, it should have no bearing on how well it performs between the sheets.
