Seeking Tips on Introducing a New Fantasy to My Vanilla Wife I (30M) want some advice on how to slowly introduce a new fantasy to my wife (31F). Some back story. We have been together since HS.

Total of 12 years. We have great passionate sex even until this day. (Although it has slowed down on frequency). I've always known that I have a strong desire to see her with another man, a fantasy that makes my heart race just thinking about it. I want to share her perfect body so badly, and watch/give a helping hand to her and a stranger or bull. However, she is extremely vanilla and has no idea about this side of me.

I want to approach this very delicately and gradually, without directly asking her if she'd be open to it. Because I’m afraid she would see me so much differently and be really upset. Are there any subtle ways to hint at this fantasy or gentle steps I can take to warm her up to the idea? I'm hoping to make her comfortable and curious without overwhelming her. I almost want it to be her idea like the movie inception (would be so much easier)

Any advice or personal experiences would be greatly appreciated. Thanks!
