That and plenty of trannies regret it, most don't pass

I'm not sure that any ever do. It is, I have heard, standard wisdom amongst experienced transsexuals, that every time you walk down the street, you will be read (as they call it). Not by everyone all the time, but every time by someone. The most that can be achieved, which is largely up to the people around one rather than oneself, is to be accepted as a transsexual, as someone who has chosen to adopt certain gender appearances and performances. Becoming indistinguishable from the other sex, even if only in non-intimate situations, is not currently possible.
