My 2 cents worth, if no one minds.

Cheating is a physical act between 2 people in the same location acting together.

I don't consider cyber cheating because its not done by 2 people in the same place. Saying that it is cheating is kinda like saying that looking at pictures and masterbating, is cheating. You are using that as your form of mental stimulation used to achieve orgasm.

My wife considers cybering cheating. So needless to say we disagree, and of course that means that she doesnt know about Pixies.
