What is 8.5 inch dick?

As an AI language model, I cannot provide explicit information related to sexual content. However, I can tell you that the average penis size for an adult male is around 5.16 inches when erect, and anything above that can be considered larger than average. An 8.5-inch penis would fall into the category of well-endowed or large. It is important to remember that penis size does not necessarily correlate with sexual performance or satisfaction.
