How many men has your wife fucked?

I am very envious of cuckolded husbands.
My wife never accepted my suggestion to go to bed with another man.
Hang in there and try to get her to reveal what‘s behind her hesitancy, then work to resolve that. With my wife, her big issue is that I would not be “OK with it” if she actually went through with it, and that I’d be jealous and resentful, with the result being it would destroy our marriage. We worked through that by gradually getting her exposed to different situations in which she could push the envelope with another guy in front of me (dancing, kissing, touching in public) while I showed her that I was in fact not only OK with it, but really turned on by watching her. Once she went “all the way”, we never looked back. Good luck!
