Kimberly, you have an extremely supportive spouse who has put up with a lot so that you can cross dress. Yes, there are some here who say that CDs should dress whenever and wherever they want, damn the consequences. But you seem like someone who cares about his wife and her feelings.
Why not surprise her and suggest a couple costume where *she's* the female one and you're her man--e.g. Romeo and Juliet. I'll bet it would mean a lot to her. Sure, it's less fun than being a girl, but you might be surprised at how much joy you'd get from making her happy. (If she's neutral on the idea, you can just drop it..)
