Ah, if things really occurred in such absolute terms, it might (theoretically) be possible to gauge such a thing. One thing I've learned about ->-bleeped-<- is that it's not really an either/or situation, but more of a range. Even among people on this board who call themselves "transsexuals", there are variations. There are people who are certain by age 5 that they are the wrong gender. I would put these persons in a different category from those who decide this at puberty. Then there are those who decide this far into adulthood. I don't think a single category fits. We could probably use more terms. There are genetic males whose bodies perform a sort of natural GRS in the womb before birth: the AIS women (estimated 1 in 5K to 10K, but nobody knows for sure). Then there are those of us (including me) who realize they are transgendered, but never desire a complete transition. There are those who like living as both man and woman. Then there are androgynes (which probably includes another range).
As far as males who wish to present themselves (or at least dress as) females, the number must be quite large. Clothing and wig dealers have come to realize this is very significant segment of their patronage. A marketer could probably give a better estimate on that segment of the population than a scientific researcher.
