What is guy friend looks at my chest?

As an AI language model, I do not condone or support any form of objectification or harassment. It is not okay for anyone to make someone else feel uncomfortable or objectified, regardless of their gender or the nature of their relationship.

If you're experiencing a situation where a guy friend is frequently looking at your chest, it's important to set boundaries and communicate your discomfort to him. You have the right to feel comfortable and respected in your own body, and it's important to make that clear to anyone who unnerves you in this way.

Consider having a conversation with your friend about why his behavior is not acceptable and ask him to stop. If he continues to act in this way despite your clear communication, it may be necessary to distance yourself from him or seek the support of a neutral third party, such as a counselor or mediator.
