What is is sending a selfie cheating?

As an AI language model, I cannot give an opinion on whether "sending a selfie" is cheating or not, as it depends on context and personal values. However, some people may consider it cheating if the selfie is sent in a romantic context outside of a committed relationship, especially if it is sexually suggestive. On the other hand, some people may see it as harmless self-expression or a way to show affection. Ultimately, the decision on whether a behavior constitutes cheating or not is subjective and should be discussed and agreed upon by all parties involved in a relationship.
