Each part plays a crucial role in both sexual function and urination.

b. Normal size variations

Now, let's talk about size. It's a topic that many are curious about, but remember, there's a wide range of "normal."

According to a comprehensive study published in the BJU International (2015), the average erect penis length is about 5.16 inches (13.12 cm), with a circumference of 4.59 inches (11.66 cm). But here's the kicker: the range of normal varies significantly! Source

A more recent meta-analysis published in the World Journal of Men's Health (2020) found similar results, with an average erect length of 5.5 inches (14.02 cm) and a circumference of 4.6 inches (11.66 cm). Source

Interestingly, a study in the Journal of Urology (2013) found that only 55% of men were satisfied with their penis size, despite most falling within the normal range. This highlights the importance of understanding what's typical. Source

Remember, these are just averages. The Archives of Sexual Behavior (2021) emphasizes that there's considerable variation in penis size, and what's considered "normal" spans a wide range. Source

So if you're worrying about size, chances are you're well within the normal range. It's important to focus on overall sexual health and satisfaction rather than just size.
