Although I would never go so far as to say that flirting is a form of cheating, I don’t believe that flirting is harmless either. When you’re single, flirting is often how a romantic relationship starts; it implies there's a sexual chemistry there. Then again, flirting is fun and a completely natural way for people to interact. So is flirting just inocent fun? Where do you stand when it comes to flirting once you’ve committed to someone else?
