It was pointed out in an article I read that one male on male sexual experience does not make a man gay/homosexual. Throw in the fact you told your wife you were en femme and it may seem more remote than declaring bisexuality. One of the issues that can arise by announcing your bisexuality is she may perceive her intimate relationship with you in a different light. When my wife and I had "The Talk" a long time ago she told me not to buy her any more lingerie because she imagined that I was imaging wearing her lingerie when we were intimate. It put a real damper on things for some time. I think a partner is more apt to think her or his partner is daydreaming about a person of the opposite sex who is unattainable than a person of the same sex who may be attainable.
If I had to take the fallout from revealing anything it would be the cross dressing.
