We've seen the Crossdressers wanting us to know and once you know you can't undo it but you can bury your head in the sand and ignore it and not be a part of it in any way.
But for Wives and Girlfriends of Crossdressers would you rather he kept it a secret from you?
Personally I'm glad I know as would hate to think of him keeping secrets and Crossdressing behind my back.

It is much better for partners/wives to know if that is possible - I know that some tgirls feel that it isn't. However it then can become an even bigger problem if ( as seems common ) the wife finds out because then there is not only the dressing as an issue but also the lies and deceit.
