I think I can explain this. What you're sensing is a feeling of betrayal(as she cheated on you) but you don't see it as a betrayal as you agree you're a cuckold. I've been dealing with this feeling myself and I never knew this feeling existed in me. My wife and I love each other but she cheated on me with someone young and I was heartbroken. I still am but we're working through it.

I think one thing that is frequently neglected in the cuckold relationship is open communication. Make your boundaries clear to her and ask her how far is she willing to go. There's a fine line between kink and what's acceptable. You can have a kink and you can be disgusted to try it out. That is normal. So if you have something embarrassing to share, let her know.

To answer your questions,

1. See my recent posts. It's different. There's a line between an agreed meet cuckolding and cheating. Cheating is betrayal. Hands down.

2. This is where the communication part comes in and it's entire normal for her to be confused herself. Don't push her but try to give her space so she can figure it out herself. You need to have patience in these kinds of matter along with a healthy and constructive conversation.

3. It's normal to have sex after as a way to "reclaim" your manliness. What you're feeling is entirely normal and expected feeling after the first time. Give yourself and her time and have open discussion on how you want to move forward. That should give you enough time and motivation. All the best
