No. It is not a temptation. It is a recognition that you will always be tempted and will eventually give in. It is unfortunate that your wife does not want to understand crossdressing well enough to find a less destructive way, not to mention a more realistic way, of dealing with it. Just the same "professional help" is not a bad idea. If there is ever going to be a better understanding on her part, you're going to need the credibility of an expert in your corner. And by expert I mean someone with training and experience in dealing with gender identity issues, not a "marriage counselor", generic counselor, or clergy.
Good luck to you, Judy. You will be in my prayers tonight.
Hugs,
