Dear Sex Doc,
How long is the average penis?

Dear Mean Male Member,
This is one of the most common questions I get from men. There is a perpetuated myth that the bigger the penis the better. Or, that you need a large penis to satisfy a partner. This is definitely not true!
The average size of a flaccid (limp) male penis is between 3 and 3.5 inches. The average length of an erect penis is 6 inches. In fact, 90% of men have an erect penis between 5 inches and 7 inches in length. That means that 5% of men have an erect penis a little smaller than 5 inches and an equal number of adult men have an erect penis longer than 7 inches.
Most people don’t know that the vaginal canal varies in length as well. The average length of an unaroused vaginal canal is 3 to 3.5 inches. When a woman is aroused the average length is between 5 and 7 inches (the same as the penis!). So, if we are talking about penis-vagina sex, having a large penis (longer than 7 inches) really doesn’t matter.
Best regards,
Dr. Brian Parker
