As for the natural urge—-
Studies show that women largely have responsive desire. I have some natural desire and initiate sometimes but largely even then it’s because we have been more affectionate around that time or have had extra emotional connection.
For some women, sex can also be transactional. Maybe not even consciously so. It is always my suspicion when men come and report a dead bedroom, yet their ws seemingly had a very sexually charged situation with the ap, I often believe there was some unrealistic expectation of what the payoff would be.
What I mean by that even may not have a lot to do with the AP. It certainly did not in my case.
In an affair there are various stimulants. One, it’s forbidden, so of course the adrenaline that you are doing something you shouldn’t be.(which we can be replicated in marriage by occasionally taking risks - on hikes, long car drives, etc)
Two, the ap isn’t often someone we know in a deep way and we project things onto them- oh he is romantic, or he will cherish me in a way that I never have been. Not in all cases, but in a majority of affairs that have been studied the payoff for women is about emotions and unrealistic expectations, escapism. Three, there is instability so there is a lot more effort to keep this unstable thing going for whatever pay off they are seeking and it’s really just their own narrative they are putting on it. Anyway, that’s my view of why someone could be more hyper sexual in an affair.
As far as building a better physical connection- if you all aren’t affectionate, change that habit and be intentional about it without the expectation of sex. Embrace more, kiss more. Give each other massages. Both of you should become more intentional about non-sexual bids for affection.
The other thing that surprisingly helped us in the aftermath of the affair was we had gone to one of the Gottman conferences and the best part of it were these question cards we took turns with. You can get the app that has them or they sell them as a card deck. Take an hour here or there and do this. It’s a great way to spend time in each others emotional world and while the questions seemed simple we had conversations that were enlightening and very connecting.
Go on dates, trips, add novelty where you can.
I suspect that if you strengthen your emotional connection, and non-sexual physical affection, this will help. Also- I can understand how over time you have probably stopped initiating because of her lack of interest being so deeply rejecting. We had to have a lot of discussions around in order to overcome that to create a system that creates less risk for both partners.
It sounds like things are moving in the right direction. At least she sounds willing to work on it.
