i think if u have a bf/gf then u wouldnt want to flirt with someone, even if it is human nature and im sure if they flirted with someone they wouldnt want u to flirt with some one so i voted it cheating even if it is human nature...
Well, it really depends. Flirting is really just human nature so sometimes it can be just natural and unintentional. However, if you flirt on purpose or if you are aware of it and don't stop, then yes, it is cheating. Why flirt with someone if you are already in a caring and loving relationship? If you really want to flirt with other people, then why are you still in a relationship?
