Do you think cyber-sex is cheating if one couple is dating?

I have done it with a couple of people, but I saw it as what the heck. I've been preserving myself for far too long and I don't know if what I was doing had any meaning. I feel I have betrayed my Ideals, but in real life if she was standing in front of me, I would not mingle. I feel I betrayed myself and my code of honor. Its something people will not understand but very few Knights.
