Wife sharing and cheating fantasy?😳

Anyone else get turned on by the idea of wife sharing or cuckolding? Even just the idea of my husband getting jealous of me for flirting, then punishing me in bed.. lol. Idk if I can tell him about this.. We both agreed no threesomes.. we joke about it though, or joke about cheating.. I kind of wish I could tell him.. he doesn’t even know I look at porn either.. it’s just a fantasy I like thinking about though... being fucked by multiple guys or being forced to watch my husband fuck another girl... I think in real life that may crush my heart though. Not sure why it turns me on, maybe because we’re completely monogamous? Anyway I could live out the fantasy without other people???
