Thanks for your post. Unlike others who appears to be threatened by my view, and have immediately resorted to personal attack, you've actually taken the time to post an honest response. It's refreshing.

Do you know the meaning,definition of immoral>moral?Please look them up or read on,then maybe rethink your position.
It's a philosophical question. To me a code of morality is a code of expected conduct that is designed to make interactions between individuals fair. At issue here is that sexual relationships are inherently unfair, and no code of conduct can make them fair. In fact, attempts to do so are sure to wind up being far more unfair than simply letting things run their course.
For example, measures designed to prevent cheating tend to be primitive and draconian--this is the source of the argument for things like female genital mutilation in the Middle East. Even here, under our old rules of divorce pretty much everyone came to the conclusion that it was unfair to punish adultery, so we revised our rules to favour "no fault" divorce. Now the only consequence of adultrery is a faster divorce--perhaps that's not even punishment but rather viewed as benefit by some.
Immoral-violating moral principles; not conforming to the patterns of conduct usually accepted or established as consistent with principles of personal and social ethics.
By observation infidelity is commonplace in our society. I linked a study up thread that indicates that at least 40% and probably much more than 50% of people engage in it. Moreover it's unlikely it was EVER anything less than commonplace and normal behavior. If you look at the amount of bandwidth that adultery gets in literature and art it's always been with us--many of the oldest stories we have, like Odyssey and Helen of Troy, are stories of adultery.
We know it's widely practiced today, and that it's been a lively topic of discussion since we were able to write down stories, so it's likely always been that way. It's plainly a generally accepted code of conduct. So commonplace that in fact it must be the case that many of the people here arguing against it actually engage in it.
I have a fundamental problem with labelling common, everyday, normal behavior immoral. That led me to look at the issue personally, and try and understand why it is that it's labelled immoral but at the same time practically everybody does it. The conclusion I reached is that we're all fundamentally hypocritical on this point--we all want to call it immoral when someone else does it, but none of us want to stop.
In the end I realized that this hypocrisy is inherent to sexual relationships, and therefore moral codes fail to deal with the issue properly. They do not bring any fairness to the relationship, in fact, they simply cause the unfairness to spill over from the sexual relationship itself into other areas of life. Sometimes in very brutal ways.
