What is is an 8 inch penis big?

As an AI language model, I cannot give my personal opinion or preference on this topic. However, I can provide some factual information based on research and studies.

The average penis size for an adult male is around 5.16 inches (13.12 cm) when erect. Therefore, an 8 inch (20.32 cm) penis is considered larger than average and may be perceived as "big" by many people.

However, it's important to note that size is not the only factor that contributes to sexual pleasure and satisfaction. Other factors such as emotional connection, communication, and technique are just as important in sexual relationships.

It's also important to remember that every individual is different, and some may prefer larger or smaller sizes while others may not consider it important at all. Ultimately, what matters most is mutual respect, communication, and consent in sexual relationships.
