We all have our reasons for doing what we do, but I agree with Laurana that we shouldn't be lying to our wives. Crossdressing on the sly is a bit like having an affair with another woman.
The only logical reason to hide our crossdressing from our wives is the fear of divorce or rejection. Or at the least, loss of intimacy.
We can't all tell our potential wives before getting married, some of us got the urge well into the marriage. It's awkward after thirty years of marriage to say "Honey, by the way, I like to prance around the house in women's clothes, makeup and high heels while you are at work.", but it's best if we can find a way.
You're going to get caught eventually if you don't tell.
Most criminals start out with that thought.4. Never being found out and never having to tell
