How do I convince my wife..?

Male
Hello, first time posting here. Me (M25) and my wife (F32) are together for a year now and I really would love to share her with a another Male, but I’m afraid of telling her, even though I tried the questionnaire and she is no way wants to try threesomes etc.. I don’t want to ruin the relationship but I really can’t get over this. I’m trying to come up with similar subject and she dosent like it. I propose to her to start an only fans for fun and she was positive with it. She also said that she doesn't mind being topless at the beach. Kinda confused 😅
Please write me advise.. much appreciated
