I think I want a threesome

My husband was joking about it some time ago, we’ve been married over 3 years. Sex is bomb, I love him, but I’m super jealous so idk how that would work. Lately I’ve been having dreams about having a threesome with another girl, never told him about it. I kinda want to try it with a girl, just bi-curious and have my 😻 eaten while he F***s me. We don’t have someone to ask, id prefer a stranger to never see her again, just in case I’m crazy jealous but damn how do we find someone and how do I know it’s the right thing😔
