It's not like back in the day when society had a set of standards that was on display everywhere as far as thee eye could see, and it was what everybody expected and aspired to be. It's not Leave it to Beaver anymore. The world has moved on since then. A lot of lines are blurred when looking from one couple to the next. Like I said before, are swingers cheating? Similarly, is it "cheating" if the couple in question has an "open relationship" (which I don't agree with, btw)? Polygamists don't think they're cheating, but do you think polygamy is cheating?
I think the answers you're going to get are purely subjective, regardless of how philosophical we try to make it. I know I'm trying to play the devil's advocate, but really, my yes/no answers are really what I feel. I would say for me, if I knew that my significant other would be hurt by whatever I may have done (take your pick from your specific options in your first post), then I would seriously consider curbing that behavior that she would be hurt by, regardless of my personal opinion or belief on the matter. Such is the sacrifice I would make for my significant other if I was in a declared committed relationship and was dedicated to making it work.
Our thoughts and opinions are a product of our experiences and that's what you're going to get. You'd have to do a serious long term study over millions of couples to get an idea of what the "generally accepted definition of cheating" really is. Where's Kinsey when you need him?
