From everything that I have read statistically there really are more m2f then f2m cders. I think that one of the reasons for this which has already been stated is that women wear mens clothes all of the time so it seems fewer of them are true crossdressers. Additionally you hear from more male to female cders because society is so much less accepting of us so we need so much more support. Then there is always the popular opinion of "why would anyone want to be male when being female is so much more glamorous and sexy." I'm sure that I am wrong on this point but I do know that if you read any studies there are many many fewer m2f then f2m.
