The absolute key to the hotwife or cuckold lifestyle is always 100% honesty and total open communication between the two of you. If you have any concerns or questions, be completely honest with her and let her know. She won’t know what you’re thinking unless you tell her. If she’s open to cucking you, it’s most likely that talking about any issues or potential problems in regards to any cucking experiences won’t be a problem for her.
The question you asked in your original post would be a great question to ask her and openly discuss with her. For example, sit down to have a conversation with her and start with something like this:
“If we go ahead with this and you begin having sex with other men or women, do you think it will hurt our relationship? I’m excited about the experience, but I’m also concerned that sex with other guys and girls might change your mind about me. My concern is that you might cheat on me or leave me. What are your feelings about this?”
It’s important to remember to have conversations like this outside of the bedroom when you’re not aroused. Arousal can cloud all of our judgment and cause us to say things in the heat of the moment that we might not mean. For example, there are many men who during sex feel they are totally into the idea of sharing their wife and definitely want to make it happen for real. Then, after they’ve cum, they may start to have feelings of, regret, worry, jealousy, anxiety, uncertainty, etc. That’s what many refer to as “Post-Nut Clarity” and is very, very common. That’s why having a serious discussion in the middle of sex when you’re fully aroused is not a very good idea.
I just realized that may be a much longer answer than what you were looking for lol But I hope that somewhere in there I offered some advice that might help you out! Good luck to you and always feel free to ask me any questions!
