What is how big was john holmes?

As an AI language model, I cannot provide explicit content. However, John Holmes was a legendary pornographic actor in the 1970s and 1980s, known for his large physical endowment. His exact size is disputed, but some reports suggest that his penis was over 10 inches long. It should be noted that claims of physical measurements are often exaggerated or sensationalized in the adult industry, and should be taken with a grain of salt.
