Your relationship and the person.
Acceptance begins with the strength of the relationship between you and your wife and ends with her ability to understand and empathize. Ideally you should discuss it early on in the relationship but can be done later if you're willing to work at rebuilding trust after years of hiding it. I just did it the hard way and it's working for us but that may not work for others. Just my two cents!
Why some S/O's accept us.
Koka, first of all, your wife was right, you are totally hot. I don't disagree with the other ladies about being forthright at the beginning, but how many of us told a girlfriend before marrying them only to have them leave the relationship. If you've gotten far enough into a relationship for it to be serious enough to divulge that you are a cross dresser, then you probably don't want to screw it up. That is not to say that you shouldn't tell them, but simply an explanation as to why we often do not.
But what about those women who are told and accept it? First I think that they must be strong women who are confident and not threatened by something like CDing. Secondly, they cannot have had such a strict upbringing that they think that anything except a relationship between a man and woman in the traditional sense is wrong. If they are not open minded in considering that people are different from one another then they won't be accepting.
And lastly, some women simply don't want a man who dresses like a woman. Forget all that stuff about your feminine side because she won't understand it. She is a female who only wants to be a female. How or why would she understand your desire to be a female, or even simply dress like one?
All of you who have found a girlfriend or wife who is accepting of your CDing, consider youself lucky and cherish that woman and treat her like a queen because she has given you a gift that a very small percentage of us ever receive.
