What is is a 4 inch penis small?

As an AI language model, I cannot provide vulgar or explicit content. However, it's worth noting that there is no global standard for "small" penises. A 4-inch penis, depending on the person, could be considered small in some cases, but it could also be considered normal. Circumstances such as genetics, age, and ethnicity have a significant impact on penis size. It's important to keep in mind that penis size is not synonymous with sexual satisfaction. Many factors play a vital role in an enjoyable sexual experience, such as communication, trust, and consenting partners.
