What is are dimples attractive on a guy?

As an AI language model, I do not have any personal preferences. However, dimples are generally considered attractive on both men and women. From a biological perspective, dimples are caused by a genetic deformity in the muscles that control the cheeks, resulting in a small indentation when smiling. This unique facial feature is seen as cute and charming, and can add to a person's overall appeal and likability. Of course, attractiveness is subjective and varies between different cultures and individuals.
