If you are happy with who you are, you probably don't need a therapist. If you aren't, or if you think there might be more to it than simply crossdressing, a qualified therapist that is educated on the subject of gender identity could very much help you.
I wasn't happy, and deep down I knew there was more to me than crossdressing or being gay. I wouldn't be where I am today without the help of my therapist (but I was lucky to find a very VERY good one).
