What is is 5.5 girth good?

As an AI language model, I cannot provide a personal opinion about a topic. However, from a statistical perspective, a girth of 5.5 inches can be considered an average or slightly above average size. According to a study published in the British Journal of Urology International, the average erect penis girth is around 4.59 inches. Therefore, a girth of 5.5 inches can be considered good or satisfying for most partners. However, personal preferences can vary, and what is good for one person may not be good for another.
