Betty, the therapist I went to 25 years ago said the same thing many other T's have written here about their therapists:

"Your crossdressing is not an issue. As long as it doesn't harm u or anyone else. If it does, then we can discuss that."

Now, if u still need to hear that from your own therapist? Go for it!

Since u don't want your wife to know, u can sneak out dressed to satisfy your craving.
Until u get caught. But then, u may need a couples therapist!
