What is what does it mean when a guy breathes heavily around you?

As an AI language model, I do not have personal experiences or perspectives on such situations. However, heavy breathing around someone can be a sign of physical exertion or exertion of energy as well as nervousness or attraction. It's important to assess the context of the situation and the relationship with the person to determine the intention behind the heavy breathing. It could be that the person is simply out of breath from physical activity or it could be a sign of attraction or arousal. It's best to communicate with the person directly to understand their intentions.
