I been there and I think if you are near the same situation as I was, you should allow her to go with what she wants to do. In our case it was a big leap to get my ex to try it and once she did overcome all her fears and worries and be comfortable with it, then for me to say I don't want her to do it anymore is really a rough thing. The ideal for most cucks is for their hotwives to take charge and if she finally does, then you say you don't want that anymore is too contradictory and jerking with her emotions. It seems the old adage is true in your case "be careful what you wish for"
