Yes I did notice this when I first went to a CD group. As everyone was getting ready several constantly spoke about their female side in the third person. One said, 'Tonight I'm taking Susie to the this pub.' It puzzled me at first assuming he had a girlfriend. But it was his female persona.
For me there is no differentiation. I use Marie as a feminine name because I like it and I suspect if I'd been born a girl I would have been called Mary, so it almost fits. Also, my given name is actually both female and male with slightly different spellings but I want to get away from it.
