For some reason I find this thread compelling, perhaps because it has so much resonance with my life. Much of what you describe about her suggests she has profound issues with self esteem. Even the way she presents herself as extremely kind and high performing in public suggests that. And I reckon the rejection of her sexually as she begged you for sex exacerbated her self esteem.
My advice to you about marriage was based on my own experience with a wife who suffers self esteem issues. It was my opinion that part of what was driving her low self esteem was a lack of sincere engagement by me in terms of the emotion of our marriage, so I searched my heart and re-found the things I love in her, and then I set about showing her how I love her through my actions, consistently over time.
But there is a denial element to this thread that is troubling.
Every single day I am faced with the reality that my wife isn’t sexually attracted to me, but she was to him. I told her that, and she says that’s completely not true. That she wishes she could make me believe that the sex was not that important to her during the affair.
I told her it’s just ME that she doesn’t want to act like that with because she’s not attracted to me. That really pissed her off. Then I reminded her of the fact that she happily fucked another man, and she threw back the usual “the appeal of my affair wasn’t sexual! I’m sorry that’s your takeaway, but it’s far from the reality of it!” Then she got mad and went to sleep with one of the kids...
Swap "long distance running" for sex. Back in the days of dating, the two of you used to go for 20-mile runs several times a week, egging each other on to run fast, laughing and having fun. Even after you were married. But at some point the running tapered off to only an occasional slow jog, barely a shuffle, to the end of the driveway and back.
Then, she meets another man. He falsely convinces her that he enjoys talking about some of the same lofty concept stuff she enjoys. Soon they are out running together, maybe not high intensity 20-milers, but at least 10k a couple of times a week. She enjoyed the runs enough that she kept joining him for more runs, and by all appearances she would still be doing this if a third party had not come along and put a stop to it.
Now that she has lost her other running partner, she is back to the occasional grudging shuffle out to the end of the driveway and back with you. You tell her you want more, and she tells you she wants it too and will try harder, but invariably each time you ask, it's the same thing.
She tells you, "I'm sorry, I just don't like running any more. I have zero desire to run. I am physically incapable of running father or faster. This shuffle to the end of the driveway is as much as I will ever be able to do." "But you ran 10k's a couple times a week with that other guy. You are clearly able to run if you want to, and you clearly wanted to run with him, but you don't want to run with me."
"I wish I could make you believe that running with him was not important to me during our affair."
Hmmm. If talking about philosophy was important, and he loved talking about this, it seems you could have achieved that without running 10k's with him a couple of times a week. You weren't forced to run. My takeaway is that you enjoyed the running part enough to keep going back for more running.
"The appeal of my affair wasn’t running! I’m sorry that's your takeaway, but it’s far from the reality of it!"
Hmmm. You chose to go running with him of your own free will. Prior to the affair, you had all but stopped running with me. During the affair, you ran 10k's with him multiple times per week. Since the affair, you have run a 10k with me zero times despite my repeated requests. Clearly, running with him -- as opposed to running with me -- was part of the appeal of the affair. Perhaps not the only appeal, but certainly part of it.
There is a rug-sweeping element to all of this, like she wants you to simply let it go away.
Finally, there is this:
As far as oral sex... none since DDAY. She hasn’t gone down on me since March of 2016, I remember that because it was my birthday.
Have you asked her for oral sex prior to PIV? She may not want you to do oral on her, but she is clearly capable of doing it on you. Has she specifically said "no" to a request?
