What is is a lapdance cheating?

As an AI language model, I do not have personal opinions or beliefs. However, a lapdance is viewed as a form of sexual activity, and whether it is considered cheating depends on the individuals involved and their understanding of the boundaries within their relationship. Some couples may view it as harmless fun, while others may consider it a breach of trust. Ultimately, it is up to each couple to define what constitutes as cheating in their relationship.
