Well an extramarital affair is having a relationship outside of your marriage, so swingers are included in that.

Only in a pedantic sense. But, I think most understand it in the common usage sense.
But I see where you are getting at and yes I agree that is immoral. However I also believe in the saying "There's an exception to every rule" and
I am sure there are reasons for having an affair that may not be moral but where I couldn't say that I might not do the same thing if I were in the
same situation.
Know what I mean?

Even if your reasons are not 'immoral' to you it doesn't mean that your subsequent actions are not immoral. But surely lying and cheating behind
the back of a person you made vows to just to get some sex is immoral whatever the reasons are that you are doing it?
After all, if you are unhappy with the relationship you can walk away. Having an affair is basically wanting your cake and eating it. What exception
could there be to make that kind of behaviour of good moral standards?
