Guys, another thing that occurred to me while answering that post-
I did not know why I felt the way I did sexually and how much was me or him (better to think it is him, right?)...I can see how a woman might wonder if sex with another man would make the difference (which of course it would, new, bad, hot...).
I am only saying, try not to get hung up on the contemplating OM thing (unless there is one and that is different)...I mean it is pretty horrific for her to say it out loud but the W is just trying to figure out wtf is going on with her. If she crosses the line, that is a different story and sex was NEVER worth the possibility of breaking up my family (although my not cheating didn't seem to improve my sitch anyway but that is my personal boundary).
