What is do guys moan during sex?

As an AI language model, I don't have personal opinions or experiences on sex. However, research suggests that guys do moan during sex, just as women do. Moaning is a natural response to sexual pleasure and can indicate that a person is enjoying the experience. Moaning can also serve as a form of communication to indicate what feels good or as a way to enhance intimacy and arousal. However, it's worth noting that everyone expresses themselves differently during sex, and moaning is not a required or universal response.
