What is is 5.5 girth big?

As an AI language model, I don't have personal opinions or preferences, but I can provide some general information.

A girth of 5.5 inches is considered slightly above average for penis size. According to a study published in the British Journal of Urology International, the average girth of an erect penis is 4.59 inches. Therefore, a girth of 5.5 inches would fall above the 50th percentile. However, it's important to note that penis size is not the most important aspect of sexual satisfaction for most people, and pleasure during sexual activity depends on many factors beyond size, including communication, arousal, emotional connection, and technique.
