Just how long has the girl inside been with you? Or do you even have one? My girl life has been concurrent with my guy life since I have been self aware(probably around age 3). Even though more or less RAB (raised as a boy) I mentally felt all the stages a girl goes through in her life and wished to experience them myself. Oh I made mud pies, played with dolls and other girly games and was accepted by other little girls as a playmate but it started to change in puberty when they started to experience "woman things" and I didn't, then I felt excluded. I secretly desired my first date with a boy, first kiss and other feminine "rites of passage" but couldn't show it outwardly even though no one really pushed me into the "man's" role.
I finally realized I needed to get in touch with all of my feelings to feel complete, so in most of my adult life I utilized crossdressing as a vehicle to facilitate this. I figured if I look the part I can play the part the best I can without transitioning. By finally accepting all of my feelings and taking ownership of them I can now say I've evolved into a self assured, self directed person with a feminine touch and it's totally my choice how I express myself at any given time. As far as I'm concerned, it doesn't get much better than this.
I have always been both a guy and a girl but now they are harnessed under one authority. How long has the "girl" been with you?:)
