Yep, that is true. It is cheating. But, you know what? It is a heck of a lot less damaging than sleeping with another woman. Because society is very clear about the boundaries of marriage. Sleeping with another woman is wrong. But for crossdressing...that is subject to a wide variety of opinions. Is it wrong to be secretive and dream of the woman I created? Sure, it is a little wrong...but does it really compare to having a full-blown physical affair? There are some women who think so...and many others who realize that it is just another goofy thing that men do. Women do goofy things, too.
For example, romance novels are female porn. I'm being serious. They give women the exact same feelings of fleeting joy that an X-rated porno does for men. That is because men and women are very different in this respect.
Do I feel uncomfortable when my wife cuddles up with a Romance novel? She does it ALL the time. Do I find it threatening???? Sure, it is a sign that our lives are not perfect. But it is okay, because I have CDing, and it serves the same purpose for me. A temporary escape that makes me happy.
And to answer an earlier question about whether I would hav had an affair if I was not a CDer...ALL MEN GET TEMPTED at some point in their lives. Whether or not he acts on it depends on the exact circumstances of the temptation, and the ebbs and flows of life situation, and a million other factors. So in my case, the desire to CD took a higher priority, and I resisted.
