You disgust me.
I have never cheated, but I have flirted with the intent of cheating before on several occassions… I need to learn more self-control.
I take the same stance too. I might love my partner, but for me it’s more a matter of contractual morality. Despite the claims of polyamorists, relationships in our society have the implicit assumption of faithfulness in them. When we have a relationship with someone, we agree to be faithful. Cheating is just a form of high deception, and I won’t do that to my partner.
I don’t think you really understand what polyamory is. Polyamorists are extremely faithful and honest. They are just faithful to more than one person. There are no lies or secrets or cheating in a healthy polyamorous relationship. Just variety.
Well said.
Having the occasional threesome or side partner with the knowledge and freely given consent of your partner is not cheating. There is no deception, no secrecy, no emotional wounds. Just variety. 
Yes. Once people get it through their heads that cheating is about dishonesty instead of the number of people involved, things become a lot clearer.
That said, there’s no option in the poll for “Have never cheated because I’ve never had the chance or an offer. And besides, I’ve never had an intimate relationship longer than four months, and that was 18 years ago, and I’ve only had one two-month relationship since then, so I really don’t think I’m cut out for this relationship stuff. Also, I’m a lousy liar.”
Never cheated, but I’ve fantasized about it countless times. Not fantasizing about the act of cheating, but rather about having sex with someone else, and it’s usually some specific person or another. There was a time when I seriously thought I may have been in love with someone else. I didn’t cheat, but I did tell my wife about my feelings because there was no way my feelings would leave her unaffected (I was very heartbroken and not stoic enough to hide it completely) and she had a right to know. Things turned out well, but it was rocky ground making that trip.
Choices for being a cheater, but none for being a “cheatee.” I didn’t know it at the time; tho I will say that the relationship in question was…complicated, she was a chronic liar and didn’t tell me until later-guy was overseas in the Navy. Needless to say I was not happy, but it led to a friendship anyway.
Shoot, one man is enough trouble in my life.
I’d never cheat on my Mig. There’s just no motivation for me. I’ve never cheated on anyone else either.
Haven’t had enough of a relationship to cheat on.
