Listen to MrsBlackBlowupDoll, Tiny_hubby. He's one of the most lucid guys of these forums.
Certainly, discuss your feelings with your wife can jeopardize your relationship, depending on how closed she is, but I think it's more likely to damage your relationship if you do or stop doing things that can make your wife think you no longer love her.
I understand the idea of "a man who control your sexual thoughts" is within the context of an erotic game, sounds very funny, but I think everything would be more fun if your wife is part of the game.
The challenge for those who want to maintain a marriage while unleashing sexual desires is to help the wife to break their own sexual chains. It's not an easy task, I know, but what you did to give your wife a vibrator is an excellent example of things to do for open to your wife the door for her sexual freedom (and the sexual freedom of both, as a couple).
Make a friend to control your sexuality, as a game, that's fine, but focus your efforts to get your wife to be more open sexually.
