Shared my wife with another man

My wife and I have been married for 15 years, she is 40 and I’m 57. it has always been a Fantasy of mine to share her with another man. We had our opportunity this weekend, It was a little difficult to surrender to see another man with my wife, but as it went on, it was hot and I enjoyed it immensely. I waited for him to get there first, then reclaimed her with mine. He was super nice and respectful of are boundaries and I loved watching another man inside her. My wife is hot and super sexy and it’s what I alway wanted to do for her, double her pleasure. she was blindfolded at her request and said she had fun. A day after I started having weird feelings about sharing her, and I can’t get the night out of my mind.. I keep replaying it over and over, and I have some videos that I still watch. When o watch them I get this weird jealousy inside me.Is this normal??
