I think that this is more interesting as a hypothetical question than a real one. Usually a domme uses a different name in her trade, like Cheyenne. I think that some respondents are thinking of that name rather than the real name, like Porky Rogers. The same goes for subs, my real name is not Komodo. I think that most people want a separation between their play and their life, and they want privacy in their life.

Taking the name of the wife draws attention to both in a way that probably neither of them would want.
