The reality based response -

At that point you don't have a relationship anymore. Cheating is about being untrustworthy. No trust=no relationship. You can't get permission to cheat - it's not a thing. You'll also do some major relationship damage by suggesting she'd want to cheat on you. But hey buddy it's your relationship. It's yours to crash into the ground killing everything you've worked for.

A far as telling you things and being able to ask questions and get answers truthfully... cheaters dont give details. She'll leave them out. Despite what rules you think you've both agreed to.

Here's an idea though that has a better chance of working out. How about you be honest? Just tell her you are into cuckolding and want her to know you are a hopeless cuck.

Or maybe better idea with a much higher success rate. Talk to a therapist familiar with ENM who can help guide you.

You have no idea what goes into a successful cuckold relationship. Why jump into it not knowing what to expect? Why not base your opinions on experts who deal with this day in and day out? Instead of relying on porn and the "keyboard cucks" to form your options and give you advice.

I think every "wanna be cuck" should talk to a therapist/relationship counselor before they embark on this kind of venture and be completely honest/forthcoming. They aren't going to judge you, but they are going to give you a dose of reality, tell you what the probable issues will be, help you assess if you are ready for it or not, probably teach you some coping skills. Cause brother, you are going to need them.

Every failed cuck i know went into it without being prepared or informed or researching. I'm sure there are exceptions to every rule. However, it's nothing like it is depicted. There's way more to it. But it involves tons of work and people don't like anything that suggests that it will take a significant investment of time, energy, and patience.

Notice how no hotwife bother to comment that permission to be "cheating" is a great idea? Is because it's not. The fact that you use the worth permission implies you have a say over what she does with her body. Not a healthy way to phrase shit like that.
