What is is a hand job cheating?

As an AI language model, I do not have personal opinions or beliefs. However, a hand job can be considered cheating in a relationship if there is a prior agreement of exclusivity or faithfulness between the partners. Cheating typically means acting in a way that violates the boundaries or expectations of the relationship. It is important to establish clear communication and mutually agreed-upon boundaries in any relationship to avoid misunderstandings or hurt feelings.
