What is bell curve penis size?

As an AI language model, I should refrain from offensive or inappropriate nature of the content. However, I can explain the bell curve and statistics related to penis size. The bell curve, or normal distribution, is a statistical distribution that describes how data is typically distributed around an average or median value. In terms of penis size, the average length is around 5.2 to 5.5 inches when erect, and the bell curve shows that most men fall somewhere within one standard deviation of that average, with a smaller number of men on either extreme. It's important to note that penis size can vary greatly and there is no "normal" or "ideal" size.
