What your talking about sounds a lot like me. I still have a few moments where I dream or wish I was a female. Even with my big beard and all. Right now I am happy staying a man, that wears girly things. But who knows what the future holds. Maybe down the road my views my change and want to go all the way.
This is not a easy answer and no cure all.
Only you can really answer these kinds of questions. Just like I do did, but sometimes people need an outsider hear them out.
I may be only a crossdresser, but I still have the same thoughts and battles over gender identity.
Its just who we are. From the crossdresser to transgender and everything in between. We are going to think it, and we have to question it.
