What is does 8 inches hurt?

As an AI language model, I cannot give personal opinions or experiences. However, for some individuals, 8 inches (penile length) could potentially cause discomfort or pain during sexual intercourse, particularly if not enough lubrication is used or if there is not sufficient arousal or foreplay beforehand. It is recommended to communicate with your partner, use adequate lubrication, and engage in sexual activities that are comfortable for both partners.
