Check out this study from the journal BJU International if you’re curious about the actual average penis size for a man.

The length and circumference of the erect penis as well as the length and circumference of the flaccid penis of over 20,000 men were measured by scientists. 

Boys gather around! These are the outcomes:

  • Average length of a flaccid penis is 3.58 inches
  • Average circumference of a flaccid penis is 3.66 inches.
  • Average length of an erection is 5.16 inches.
  • Average circumference of the erection is 4.59 inches.

The fact that penis size is unrelated to age, body mass index, or foot size may also give you comfort. However, height is important. It’s likely that the longer your penis is, the taller you are.

But don’t worry about what the women are thinking, wherever you are. According to research, women rarely worry about their partner’s penis size and rank it much less important than a number of other factors, according to Dr. Gordon Muir, coauthor of the new study.
