New to this looking for advice [cuckold perspective]

I told my wife about my fantasy and I just need some help. I want this to happen and I fantasy about it constantly. But I get to fueled with emotions and trying to understand them and go about everything the right way I want to be a cuckold but i also want her to be more open about it. I’ve seen she has chatted and sexted other men. But does it more behind my back it feels . I could absolutely be getting confused or looking at it the wrong way. I am very new to this and if any one has any advice please message me. I’m 28 she is 32. She does want to do it but seems like only when she is drunk and I don’t know if that is a bad thing or normal to ease her nerves about it. She is definitely more dominant. Does anyone have any ideas on how to get convos started maybe even baby steps to get more into to to ease my fears and nerves. When I get into the moment I want to be a full fledge cuck to the point I want her to have no rules because in that time it turns me on to think of that but in reality I am scared she is gunna leave me even though I trust her
