One more thing I would mention is that of all the groups of people in this entire world, we as TG/CDer's are absolutely the most misunderstood group of any by society.
Why would a man want to dress as a woman most wonder about us, and its a very legitimate question for them to ask. The answer however isn't as simple as we'd like it to be, most however that I've spoken to believe its an inborn part of us and to different degrees in each individual. What does one really know about ones own identity when they started cd'ing at 4-7 years of age? Transexual male to females have been shown in MRI scans to have a brain more similar to a females compared to the average heterosexual male, is that a choice? I think not.
The urges an average crossdresser will have to dress can be compared to someone trying to stop smoking, actually the smoking cessation would be mild to most cd'ers compared to stopping the crossdressing altogether when the two are compared. The more people come into contact and understand cd'ers, the less fear they will have of them, as was said we're pretty decent people overall.
