See answer : More often than not, having a small penis is more of a perception than a reality especially in men who are either overweight or obese. True penis length is measured from the tip of the stretched penis back to not the skin but back deeper to the pubic bone: average flaccid length is 9–10 cm (3.5–3.9 in). Despite many false claims, there are no supplements or meds that will increase penile size.
