It has nothing to do with competition. Crossdressing is odd. It is not something that comes up in the general life experience of most women. They are not threatend buys, they are confused. "What man, in their right mind, would want to dress as woman?". It just doesn't make sense. As a result it is easier to avoid this kind of relationship than engage it. We crossdressers have an obligation to try and help women understand, not simply expect it.
