Need advice on navigating swingers lifestyle

Wife (30) and I (34 M) are recently dabbling about the idea of going to a swingers event. We have been married for 2 years and have dated for 10 years before getting married. I started dating her freshman year of college and I was her first and only sexual relationship. We have had on and offs in the relationship but she largely remained monogamous to me and never had sex with anybody. During our relationship days, I initiated the idea of opening our relationship or trying swinging but she was completely opposed to it and rather doubted my love. However, in the recent 6 months, she has been very vocal about having another sexual experience, particularly sharing fantasies trying MFM and swinging with couples. During our one heart to heart convo, she really urged wanting to have one sexual experience and cannot imagine not trying sex with another person. She even mentioned she now regrets why she ever explored casual sexual experience. She initially wanted hall pass or ONS with some random person but when I proposed the idea of swinging and attending a swingers event and seeing the vibe If we like how things are going, we would be open to exploring threesomes with couples or single men - particularly my wife's sexual fantasy. I told her I feel more ecured sharing her in a MFM with me than giving her hall pass or ONS with some one.

We have a healthy sex life going with sharing fantasies around threesomes, group sex, or sharing with couples.

Should I be worried for her sudden interest in trying a different body?I have always been interested in this lifestyle and it feels to good to be true. I am both excited and nervous since this will be a new journey and we don't know what roads will lead us? So I need some guidance.
