For some that are deeply into CDing, dress completely as a woman and like to think of themselves as a woman when dressed isn't it reasonable for them to carry the woman thing further by wanting to be the woman in a male /female relationship. Of course the CD woman would want a man to do the things a woman does with a man. This would help her validate her female role more so. A lot of sexual activity can be tried, maybe disliked at first but the more it's done the person begins to enjoy and desire it.

Then their are the CDers that just like the clothes and the clothes don't push their sexual "button".
