1. Is sex (desirability, quantity, variety) the only measure of a man's masculinity? If not, what else?
No, it isn't the only thing. While badly bruised right now, I still know that I am successful, attractive, intelligent and well respected (other than by WW unfortunately). When discussing femininity and masculinity it seems like taking attractiveness/suitability for sex out of the equation would be pretty difficult. It seems to me that it is clearly the biggest factor. I think the sex aspect is also a primal thing. This won't go over well, but here goes: there is something innate in men that makes us want to protect our home and our mate from other men (perhaps because if a woman has a baby you know it is hers, but you don't know who the father is [of course now you can find out, but historically not the case]). I feel that my home and my wife were violated by another man and that is a direct attack on me. This may be caveman thinking, but most of us have at least 2% Neanderthal DNA... so lets not pretend that instinct isn't real.
However, it is also the result of a societal construct. For all of recorded history the cuckold has been an object of derision. Shakespeare's Othello is based on the mindfuck of being cuckolded (yes, I realize that the moral is actually about the danger of jealousy, but the underlying issue is his fear of being a cuckold). The term is an insult because it implies the cuckold is less of a man, that he has been bested by a rival in the sexual arena. Men have not only innate, primal needs telling them they must secure this area of their lives, but a societal view that they are less of a man if they don't.
I don't like this (and I have ruminated over it endlessly) and I wish it didn't affect me this way, but it does. It is also a matter of fairness and the WW demonstrating love and remorse etc. However, I think it is much deeper than that for most men.
2. Is sex the only thing of value a WW offers in reconciliation? If not, what else?
Not at all. All of her assurances and apologies have value. Everything she does to make me feel secure and rebuild my ego and the life we had matter. As we all know though, words don't mean a whole loft early on. Actions matter more.
3. Does nothing else bother a BH besides the sex in the affair? If so, what is it?
I may be in the minority, but the sex (other than in our bed in our house) is not anywhere near the top. The deceit, the lies... hundreds/thousands? The disrespect for me and our family. The betrayal of my confidences to OM. The fact that I was throwing myself into the marriage to try and build emotional intimacy, giving her space to deal with her "sexual issues". The fact that she flat out lied to me about her sex drive... she just didn't want to have sex with me (for reasons that she also denied were a problem when I tried to get into addressing issues, and many are objectively insane or at least completely unfair or fabricated entirely). The fact that she also lied to our daughter and neglected her in order to spend more time with OM. The fact that she spent thousands of dollars on her affair and then would say shit to us like, "no let's not eat out tonight, we need to save money" (while dining out anywhere from 5 to 10 times a week with OM) or "yeah, that's an amazing hotel, but I don't want to spend that much on a room" (while spending up to $500 a night with OM). The fact that she denied me emotional intimacy even when I was literally begging for it, and was all the while providing it to AP. The fact she began her affair when I was visiting my dad who was just diagnosed with cancer. The fact that she kicked the affair into high gear when his prognosis got worse (all the while denying me the support a spouse should give). So many other things. Honestly, I think I could deal with the PA much better if it wasn't also an EA where she fell in "love". (conversely, I also think I could deal with an EA without sex much better... the combination is a gutpunch like I've never experienced)
4. Is their willingness to have sex the only value women have? If not, what else?
I feel like this is kind of incendiary and unfair, but I'll address briefly. My WW was the best counselor in my life. Whether it be career, relationships... anything, I trusted her advice and judgment more than anyone. She was a wonderful mother and helped in raising a wonderful child. Though we became detached over the last few years, through most of our nearly 2 decades together she was my closest friend and until last December was still my closest confidant. She was always there for me, I always knew she had my back. She was a wonderful sister-in-law and daughter-in-law... my family loved her and accepted her and loved her completely (while her own family is a f'n disaster). All of these things are gone now. I don't know if they will ever come back, but I am sure it will take time.
The sex doesn't have to take time though, that is all up to her and it would send a pretty good message to me about her sincerity in wanting to reconcile and address the issues in our M. It would also do wonders for my wounded pride.
