The average penis size in the USA is a topic that has been widely discussed and debated. In general, the consensus among medical professionals and researchers is that the average penis size among adult men in the United States is between 5.1 and 5.9 inches when erect.
Although there is no single collective statistic available for the average penis size across all states or regions of the US, data from studies conducted over the last decade have established that the average is fairly consistent with a small variance based on geography, ethnicity, and other factors.
History of Research into the Average US Penis Size
The history of research into penis size dates back to the 1950s and was first conducted by Alfred Kinsey. However, the study was deemed to be insufficiently rigorous and reliable due to the self-reported nature of the results. More recent studies conducted in the late 1990s and early 2000s used more rigorous methods such as measuring the penises of participants in a laboratory setting. These studies produced more reliable results and led to a better understanding of the average penis size in the US.
Factors Affecting Average Penis Size
While the average penis size in the US is generally between 5.1 and 5.9 inches when erect, there are a number of factors which can affect the size of the penis. Some of these include geography, ethnicity, age, height and weight.
Studies have shown that men living in the northern US tend to have slightly longer penises than those living in the south. Furthermore, men of African descent tend to have larger penises than those of European descent.
Age is also an important factor in determining penis size. Generally speaking, younger men tend to have larger penises than older men. Similarly, taller men tend to have larger penises than their shorter counterparts. Finally, heavier individuals tend to have slightly larger penises than those with lower body mass index (BMI).
Penis Size Measurement
In order to accurately measure the average penis size in the US, researchers use a combination of physical measurements and self-reports. During physical measurements, researchers use a ruler or tape measure to measure the length, width and circumference of the penis. Self-reports involve asking participants to answer questions about their penis size and then verifying the answers in a laboratory setting.
Penis Size and Sexual Satisfaction
The size of the penis has been shown to have an effect on sexual satisfaction. Studies have repeatedly shown that having a longer penis is linked to higher levels of sexual satisfaction. This is because a longer penis can stimulate more areas of the female body with greater efficiency than a smaller penis. However, it is important to note that studies have also shown that penis size alone is not enough for satisfactory sexual performance.
Conclusion
In conclusion, the average penis size in the US is generally between 5.1 and 5.9 inches when erect. However, factors such as geography, ethnicity, age, height, and weight can all affect the size of the penis. Additionally, studies have repeatedly shown that penis size is linked to sexual satisfaction.
