I think you raise some good points. If you are in a serious relationship with someone, then there should always, always be communication as to what is acceptable and what is not regarding this issue of "cheating". For example, both my hubby and I agree that any kind of sex with someone else is cheating. However, if he or I looked at porn, neither of us consider that cheating. I get PMs all the time from members who flirt with me and I flirt back. My husband knows about it and doesn't have a problem as long as I don't escalate things to the next level and actually go and meet the guy. Over at Betterman's I constantly had guys who would write and tell me how they would love to fuck my brains out. And I would flirt back, also. Again, as long as it was just flirting, my hubby could care less. And if he flirted with a female on the Internet and told her how he would love to fuck her brains out, I would be okay with that, AS LONG AS he never followed up in real life. Of course, that is us. Some men and women are threatened by any type of correspondence their SO might have with someone of the opposite sex, so that is why discussions on this issue must be ongoing.
