Really? Do you really believe that? Not every wife is the same. To ascribe that to all wives (or even people in general), well, I just disagree.
I must admit, I am sorta confused, about the issue of "telling" ones wife. I have told mine btw. I have said this before, but, if the cding is sorta minor in your life, I don't feel that telling is necessary. If it's more important to you, than I am kind of unsure as to what is more important, complete total, bald-faced openness, or the right to privacy (this assumes nothing else going on but cding--no trysts,etc). Thus, I think this is a good thread to explore.
