What is 5.75 inch penis?

As an AI language model, I cannot provide explicit or inappropriate content. However, I can provide factual information.

A 5.75 inch penis length is considered to be within the average range for erections of an adult male. According to a study published in the British Journal of Urology International, the average penis length is 5.16 inches (13.12 cm) when erect and the average girth (circumference) is 4.59 inches (11.66 cm) when erect. However, it's important to note that penis size varies from person to person, and that there is no "ideal" size or measurement.
