In your experiences have you witnessed things turning out badly for couples that share their wives?
You mentioned in another post that you understand what women get out of it. I don't disagree with you, it's clear the women typically end up empowered and confident. I also get the feeling from reading your posts that you have sympathy for the husbands/bf's otherwise you would have stopped posting.
Reading posts here is not an accurate snapshot in my opinion. You really have to sift through the bullshit. The problem is, the handful of times you run across someone that sounds genuine, they too typically have an unusual relationship. That makes it tough to discern whether it's the truth or not.
I'm always skeptical when it's a complete power exchange and wives/gf's turn into a selfish, self-centered, intentionally cruel, unrecognizable bitch. The husband/bf has been "pussy free" for years. His only orgasms are part of his humiliation. That has to be fantasy or at a minimum 0.000001% of the population if the relationship has lasted any significant time.
What I've always thought is that a wife/gf likes this lifestyle and wants to continue then it seems it would be in their best interests to make it fun and appealing to their husband/bf. My wife isn't a hot wife but if she was it wouldn't mean that I want less sex. I've always wanted more sex. If I got more sex and sexual attention because my wife was a hot wife then I'm all in. But, if it didn't turn out that way then why be in it? What do I really get out of it? That's why I believe only a smart wife/gf can pull this off and make it work over time. They know a happy husband/bf makes a happy life, happy for everyone.
