I think maladaptive daydreaming does apply to some of us. We see a catalog of pretty women wearing pretty dresses and we fantasize about wearing those pretty dresses after transforming into a feminine image with wigs, makeup, shapewear, etc. The crossdressing is making the fantasy real for us. I can't imagine how I could ever crossdress without first having that fantasy (daydream).
When anything (crossdressing, golf, gambling, drinking, daydreaming......) is done excessively (excessive is part of the definition of MD - see the OP) it can cause disruption of normal life activities, including interaction with others.
But certainly doesn't apply to all crossdressers whose normal life activities are not disrupted.
