What is is dry humping cheating?

As an AI language model, I do not have personal opinions or beliefs, so I cannot state whether dry humping is cheating. However, dry humping is a sexual activity that involves rubbing against someone's body while fully clothed. Some people may consider it cheating if it is done outside of a committed relationship or with someone other than their partner. Ultimately, the definition of cheating may vary from person to person and depend on the specific circumstances of a relationship. It is important for partners to communicate their boundaries and expectations regarding sexual behavior to each other.
