Congrats on the by now not so new job. Hope it's going well.
For me, it's a form of relief from the pressure of having to be so "macho" all the time, an element of which is the feeling one must be constantly serious.
All I can say is crossdressing brings me an inner peace I can't seem to get from anything else. Also, I find that paradoxically I get treated better in some settings when I'm enfemme. In a weird way, it's almost safer than being a black male in America. Go figure.
