I read a doctoral thesis recently that summed up the hotwife (cnm) experience as being full of anticipation, novelty, and excitement. That’s what he brings.
You offer stability, consistency and pleasure.
Jordan Peterson says, we think we are unique, one of a kind, 1 in a million. If you’re 1 in a mil, you are 1 in 30 in New York City alone Since there is 30 million people. He also says, you can always find someone who is better if you compare yourself.
The other guy is a treat. Your wife values you for the stability and consistent pleasure. The things you cannot possibly give her are the anticipation and excitement. You need a surrogate for that, and that’s the other guy. He has a role, She has her role.
Shes not looking to replace you. Let her have the novelty and excitement.
