What would you say is the average penis length in your country? Does size matter? What do you think?

Many women say that it’s not so much the size of the penis that matters, but the man’s ability to use it. In addition, we mustn’t forget that what really makes us enjoy sex is our connection with our partners and how they treat us, along with many other factors.

However, some researchers have suggested that penis size is important and they studied the average length in various countries. We’re going to tell you about the 15 countries in the world with the largest average penis size, as well as the country where the penis is the smallest.

In addition, we’ll answer the question, what’s the size of a ‘normal’ penis?

“Sexuality not only refers to the sexual act but also includes a broader dimension, related to identity, gender, the role we play in society; it has to do with the decisions we make in life.”

-Karol Cariola-

The average length of the penis by country

What’s the average penis length by country? A worldwide survey conducted by the University of Ulster (Northern Ireland) investigated this question. The survey was conducted in 116 different countries. Its results suggested that Africans and Americans have the largest penises.

Although the study ranked 113 nations, we’re going to talk about the ten countries with the largest average penis size.

1. Republic of the Congo

According to the study, the natives of the Republic of the Congo are those with the largest penises, with an average of 17.93 centimeters.

2. Ecuador

Ecuadorians are located in the second position, with an average of 17.77 centimeters.

3. Democratic Republic of the Congo

The Democratic Republic of the Congo (not to be confused with the People’s Republic), is in third position. Its inhabitants have an average penis length of 17.33 centimeters.

4. Ghana

Ghana, a country located in West Africa, is in fourth position, with an average size of 17.31 centimeters.

5. Columbia

The South American country is placed in fifth position. The average size of the penis here is 17.03 centimeters.

6. Venezuela

Another South American country, although in sixth position, actually shares its results with Colombia. Indeed, according to the study, Venezuelans have an average penis size of 17.03 centimeters.

7. Lebanon

Inhabitants of Lebanon, located in West Asia, have an average penis size of 16.82 centimeters. This data places them in seventh position.

8. Cameroon

The natives of Cameroon, also known as the Republic of Cameroon (located in central Africa), have penises that measure, on average, 16.67 centimeters.

9. Iceland

Iceland is the only country in Europe in the top ten. The average size here is 16.51 centimeters.

10. Sudan

In tenth position is Sudan, a country in Africa. Their penises measure, on average, 16.47 centimeters.

Beyond the top ten

What countries follow the top ten? In eleventh to fifteenth place we find the following:

  • Jamaica: 16.30 centimeters.
  • Panama: 16.27 centimeters.
  • Nicaragua: 16.26 centimeters.
  • Benin (West Africa): 16.20 centimeters.
  • Brazil: 16.10 centimeters.

Average penis length

Now you know the 15 countries with the largest average penis size. However, what’s the world average? A group of British researchers published a study published in the British Journal of Urology International. It analyzed the penis length of more than 15,000 men from around the world.

The average was 13.12 centimeters long (when erect). On the other hand, the average length of the flaccid penis was 9.16 centimeters. Other interesting results of the study were that 2.28 percent of men have a micropenis, while five percent of them have a penis longer than 16 centimeters.

The countries with the smallest penises

The men with the largest penises in the world, according to the study indicated, are mostly African and American. So, where are the men with the smallest penises from? According to the same study, the countries with the smallest penises are North Korea and South Korea, with an average penis size of 9.66 centimeters.

Several studies have also been conducted on this subject in relation to the sexual sphere. Although the results vary slightly, Africans take the lead in penis size. The average is 16-20 centimeters when erect. On the contrary, Asians have the smallest penises, with an average of 10 to 14 centimeters when erect.

Does size really matter?

The debate about the size of the penis and its relation to the sexual enjoyment of women seems to concern men more than women. This was revealed in a study published in the journal, European Urology. In fact, the majority of the women surveyed stated that the size of their partner’s virile member was irrelevant.

Moreover, another study published in the British Journal of Urology International suggested that 85 percent of women were satisfied with the size and proportion of their partner’s penis. However, almost half of the men who participated in the research (45 percent) believed that their penises were small, despite the fact that the actual size of their members was average.

So, if you’re a man and you’re worried about the size of your penis, it’s time to start working on that concern. After all, it’ll only ruin your sex life and that of your partner.
