I think that for most it’s as “easy” to completely stop crossdessing as it is for a left handed person to become right handed. It may not impossible but even at best it will linger in the background.
I did tell my wife about my cd before we got married and at that point it moved to DADT (DontAskDontTell) and I lived with that for some decades while kids grew up and so on. Then I started to come out more and more and I think if she had pushed back I would just go back to DADT but it would not go away.
Now I’m almost completely out so it would actually be strange if I somehow put away Kelly deep in the closet. Some people already asking where Kelly is when I’m in drab.
