OutoftheDeep:
I'm using stereotypical generalizations here, but I do think that Wayward Husbands are far more likely, in the immediate aftermath (during False or Real Reconciliations) to speak derisively of their Affair Partners to their spouses, largely because the nucleus of their affair is sexual gratification / male ego reinforcement. He might have thought the OW was a "whore" / "skank" from the get go, and in fact, that could have been the Value Added Benefit the WH was seeking.
Wayward Wives (again, generalizing) tend to see an emotional nucleus to the affair, and thus, in the Fog, can cling to a more romanticized view of the AP. There is, in such instances, a tendency towards more protective language when speaking of the AP at first, because the WW wasn't primarily seeking an easy lay from the nearest phallus-bearing, language-speaking biped. That's the kind of thing "skanks" do, and most WWs don't want to think of themselves in such unsavory terms.
The horror for many a Wayward Wife who reconciles is that, with time and perspective, they discover that their Affair Partner, Mr. Romantic Bearer of intimate conversations / wine / roses / poetry, had a far more transactional view of the exchange all along.
Recognition that they were used for sexual gratification / male ego boosting can make the WW's guilt far greater in the aftermath in these cases, but it makes their Affair Fog thicker, too. The WH may have known he was a "dirty dog" all along (and may have taken Male Pride in it), but the WW did not believe, and doesn't want to believe, she behaved like a "skank", because it will hurt her Female Pride to admit this.
The irony of it all, it seems to me, is that both Wayward Husbands and Wayward Wives saw the same basic Value Added Benefit in their Affair Partner while in the Fog:
"He/She understands and appreciates me, unlike my Spouse!"
It's Ego Gratification, but the medium of exchange to assign that Value is quite different. The WH saw the Sexual Desire as the sign he was appreciated. The WW saw the Intimate Connection as the proof that she was valued. Their respective desires weren't wrong-- but their outlets for seeking such reinforcement were.
I know I'm really generalizing here and exceptions abound. Some WW's seek the sex as recklessly as a Frat Guy during Rush Week, and some WH's want romance/intimacy above the bumping-of-new-gonads.
But in my own history, and those I've seen secondhand, these seem to be the archetypes.
