It seems that every week ( even as reported in just my local tabloid newspaper) the 'transitioning' population increases, and the Transgender Umbrella ( as determined by Stonewall) provides shelter for a very wide range of demographic of people.
Yet it seems to me ( would be interesting to see statistics) that apart from young women ( mainly lesbians) transitioning to male...the largest and most rapidly accelerating group is that of older 'cross dressing' males. Most often heterosexual or married, and quite often having been in, or performed, an archetypal macho or traditionally masculine role or occupation ( been in the military etc).
This is not only as evidenced by the growing number of reports in my local newspaper, but from my own observations on the street and around town: www.liverpoolecho.co.uk/news/liverpool-news/transgender-woman-agreed-cannabis-plot-17604909
