Synesthesia? perhaps, in my case I was born premature in the mid 60's. There was nothing that would fit me but doll dresses. I often wondered why I could never find my baby pictures, always thought they were all of my older sister. That may explain why I do it, but does not explain why others do. Considering historic attire, boys and girls wore dresses long ago, boys would undergo a right of passage called getting breeched. That in itself did not lead to cross dressing at an older age. I always thought the phenomena was associated with androgen exposer during the pregnancy that resulted in behavior later on in life. Sure, I want to be a girl, but yet I am physically and sexually attracted to them at the same time. I may buy the dopamine theory but not sure if I could buy into the synaptogenesis theory of learning behavior by synaptic pruning. If not most of my life I was taught it was wrong, not just by parent conditioning but also by society and peers. In other words, is there to be an understanding of this behavior to offer a cure? At times I may have seen it as a curse, but many more times I embrace it and would not want a cure. Since man does not fully understand how the brain really works, how it can recover from injury and why there is a large part of the brain that is not in use, how could one really understand the nature of cross dressing or gender disorders of any type. Sure there may be some that have been exposed to a catalyst but that may not be true to all. Besides that, the brain is not the only organ that stores memory. There have been recent discoveries that other organs posses similar ganglion structure as found in the brain tissue. (they knew of this decades ago but recent theory is that organs may posses the potential to store memory, this may support why some who have received organs from transplants and have some memories that are not their own, not sure I buy that either but.... enough said already). I do not want to understand why, I would rather enjoy the end result.
