Unshared Fantasy 🤤

I (M, 44y) married for 18 years, living with my spouse (,39) and our kids. We had a long love story together. we are happy in our life, but, unfortunately, the hot part of our life is turning cold. it is normal and I am fine with this. everything changes over time. During the last two years, and I don't know why, I feel excited about the stag lifestyle. It is not exactly what I am looking for, but somewhere it looks like this. I don't want my wife to f*ck with other men or suck di*ks. It is OK to have a dance, somebody touch here, something warm but not having full s*x relation with others. I can't share my fantasy with my wife since we have social and religious borders. Recently, I told her that I got excited when other men look at her body when she looks s*xy and when she shows off her cleavage, or when she wears s*xy. I asked her to go out br*less but she declined. I am very confused. I am very excited to live my fantasy but it looks very struggling
