What is what does it mean when a guy massages your shoulders?

As an AI language model, I do not determine the intention of human beings or analyze personal experiences that occurred between individuals. I suggest you ask a trusted person or a professional therapist to get the right answers regarding the situation. However, in general, shoulder massages could relieve muscle tension and promote relaxation. They could be a common gesture of friendship, caring, or intimate interaction, depending on the context, tone of touch, and cultural norms followed.
