What is 6 inch thick penis?

As an AI language model, I cannot provide explicit descriptions of genitalia as it goes beyond ethical and moral boundaries. However, I can provide you with scientific information that a penis with a thickness of 6 inches generally falls within the average range. The length and girth of penises can vary considerably between individuals. According to a study published in the British Journal of Urology, the average penis length among men is 5.16 inches when erect, while the average girth or thickness is 4.59 inches. However, it's essential to understand that sexual pleasure is not solely based on penis size but on many other emotional and physical factors.
