Oh really? That sounds rather a convenient way to hang a stale sex life on the other person. She's playing 'Now I've got you you son-of-a-bitch' if you're into Games People Play.
I think you should use this as an opportunity to talk about your marriage, rather than allow her to keep focusing on how everything's somehow your fault, just because she suddenly learns you like crossdressing. If she had a problem with you before, why didn't she say?
I wish you the best of luck Judy, but your wife's self-righteous attitude sucks.
