Having been married 15 years I certainly have!


As for the question you are asking: It would depend on the state of the primary relationship. To me the immoral thing is not having sex with a married person, but acting so as to risk harm to their relationship. There are a lot of marriages where the relationship has already failed but they simply haven't split up for whatever reason. I see nothing wrong in being the other in such a situation. Trying to seduce a happily married person, though, I see as wrong.
