I want to be cuckolded, but she does not

I met my wife 4 years ago. We dated for 3, we were engaged for 1 year and got married last month.

Right on our first date, we already talked about swing and thressomes. She confessed to me that her biggest fetish would be to do DP, because she had never had sex with two guys at the same time.

As I have had the cuckold fetish for more than 10 years, so I was interested in her at the same time.

As our relationship became more solid, I tried to talk to her about the subject, sent videos, bought sexy lingerie, sex toys. But it seems that over time, her interest decreased more and more until it reached a point where she told me that she was happy only with me and that she didn't want this kind of thing anymore.

I tried to forget the subject, I focused on our relationship and I'm very happy with her. But I get frustrated for not having this fetish performed. Now that we got married, and it's still very early, I still think about it and it seems that after the wedding it has taken over my thoughts more and more. I believe that for now she is officially my wife, the fantasy of having a hotwife has surfaced more strongly.

I've already tried to understand her fears, and I have mine too. One of my suspicions is because she was traumatized because her father cheated on her ....... But in our case, it would be consensual, so there would be no problem of trust.

When she tells me about her past, I keep imagining that if we had a cuckold relationship, she would love it. According to her words, she was a slut. He had many sexual partners. I would be the perfect cuck for her, because not only would I like to see her with other guys, but I would interact with them, sucking the guys together with her, cleaning her after a creampie (she doesn't like facial cumshots or in the mouth), filming our adventures.

What's missing for me? Talk to her more, even though she says she's not interested anymore? I really don't know what to do.
