Current books I'm looking at:

The Ethical Slut

Mating in Capitivity

Opening up

Background: My wife and I have been together 8 years, married 3. We hit it a bit rough around end of year 1 into year 2 of marriage just frustrated in general. Both went into therapy and had a lot of discussions and managed to come out the other side with a completely different communication level and happiness with selfs and relationship.

About a year ago one area I felt was lacking was our sex life. I picked up "Come as you are" and we both read it. One thing that came out of it was my wife has a very strong want to be "desired", for varioua reasons

Over time we discussed, really my idea that id be okay with her flirting with a guy while she is out and even kissing/making out would be fine. Mentioned it recently before a Bachelorette and she ended up going through with it. It went well and we came out of the experience better for it.

So we have entered into that ENM territory. I'd like to do some more reading on the topic as it pertains to relationships.

Looking for the most relevant book based on the background of where we are in the transition. Additionally, we are not at a point where sex is allowed so a book with a heavy focus on that aspect wouldn't be relevant, though it's something that may change in future.

Our goals with entering ENM is strengthening of our relationship through a trustworthy and safe way to experience that thrill of initial desire in a controlled and guilt free way.

Appreciate any recommendations to assist us as we continue to process and discuss.
