Perhaps this was just a bad choice of words, but I agree with a few of the others that this smacks of selfishness. It sounds as though you want to manipulate your wife into choices she never would have made otherwise. Any relationship requires both parties to move forward to a shared position that both can accept. You can only discover your common endpoint by frequent, open communication and a lot of (that unholy word) compromise by those involved. If you can't find a common endpoint that's acceptable to both, then you have much deeper problems than just crossdressing. Keep talking, and figure out where you want to go in your lives. Then figure out how the crossdressing fits into your shared life, anything from Don't Ask Don't Tell to full sharing.
