If it gets physical.
Expressing explicit intent to engage is sexual acts with someone other than your partner is where I draw the line between cheating and not cheating. Flirting, being witty, returning a smile or saying someone is attractive is not cheating. It's inconsiderate of your partner, and can lead them to believe you're not a faithful person, but it's not actually BEING unfaithful... yet.
Sexting, sending pictures, sharing any sort of sexual-natured thing with another is too far.
True but most will agree that's radical and illegal in many countries. This sort of behavior is frowned upon and doesn't fit in with he social norm. Going off tangent a little, weren't you a believer asexuality a couple years ago? I vaguly remember you saying you weren't attracted to either sex.Just be a polygamist and you won't have to worry about it.
Flirting is highly subjective for me. I can tell when someone's a dickhead with bad intentions and when someone's just being flirty for fun; so some people I wouldn't mind it with but others it would irk me somewhat. Interesting to see how it varies.
Each couple has a unique relationship that they define. This is something you should talk to your partner about, not people on a fantasy RPG gold trading forum.

Anyway, I view anything that you wouldn't tell your partner as cheating. If you are willing to hide the truth or lie about something that has happened with someone else, I consider that cheating. Basically, if you know your partner wouldn't approve of your actions, you're cheating.
As far as this is concerned then, I draw the line when you stop feeling for your partner, or you have feelings grow for another. It doesn't necessarily have to be physical to constitute being "unfaithful".
