Penis size can vary from person to person with an average flaccid size of 9.16cm and 13.12cm while erect. The size can also vary depending on the person’s nationality with Ecuador (17.61cm), Cameroon and Bolivia having the longest average size and Cambodia (10.04cm), Taiwan and the Philippines with the smallest sizes. A micropenis is less than 5.2cm when flaccid or 9.31cm while erect. The length should be measured on the dorsal side from the root of the shaft to the tip of the glans. Additionally, multiple studies have evaluated the relation between height, BMI, shoe size or finger length with penile size; nevertheless, no correlation was found. It is important to note that while 85% of women are satisfied with their partner’s penis size, only 55% of men have reported to be satisfied with their size. The vagina has an average length of 9.6 cm which means that the average penis is longer than the vaginal canal; nevertheless the area that is thought to be important for most women’s sexual response is the outer one-third.
