Do you want bigger nipples? If not, then don't do it. Duh.

Would she have hers done for you? I can't think of anything worse than a mouthful of metal when playing with my husbands nipples.
i thought piercings for for people who like the sensations of the metal & possibly the pain of them being pulled on?
but i could be wrong..you do what u want...they are your nipples
Who was your wife talking to about having your nipples pierced? Was it you? Are you involved in the decision at all? If not, just let her get on with it.
Perhaps she is planning to attach some shopping bags to them, which would indeed make them bigger. If that is the case and you are worried about increased-nipple size, you could just offer to carry the shopping bags with your hands, which could very well put an end to the entire 'nipple-piercing' situation.
