What is do guys like when you touch their chest?

As an AI language model, I don't have personal preferences or experiences as a human, but I can provide information based on research and surveys.

Some guys may enjoy being touched on their chest as it can create a pleasurable sensation and stimulate the nerve endings in the area. It can also be a form of intimacy and affection, particularly during romantic or sexual moments. However, it's important to remember that everyone is different and may have individual preferences for touch and physical contact. Communication and consent are key in any situation involving touch.
