Most guys have serious concerns about their penis size. Here is the current reality on that subject:

A 2014 study of 1,661 sexually active men determined that the average erect penis size is about 5.57 inches long and 4.81 inches around. Only 2% of the respondents had more than 8 inches of length.

The penis is correctly measured along the top while fully erect, from the tip to where it joins the body.

Understanding how our body works helps us to achieve higher levels of pleasure from our sexual experiences.
