Last night I downloaded an ebook called The Gender Book from the official website by the author. He is intersexed and based off of his experiences as an intersexed individual and what I read in the summary before ordering it as a free download, I thought it was a reliable resource. That is, until I got to a part in his book where he talks about figuring out what your gender is , I guess if you aren't sure or your questioning and experimenting with it.
The thing that baffles me to this day is the question of whether or not gender identities really do or can change and if so, could we make them change into what we want? This book, as supportive of gender nonconformity as it seems, claims that gender identities do/can in fact, change. I am so confused, because some people...most people, who are educated in this subject, say that gender never can change. I mean, which one is it?

Is it one or the other. I don't think you can have it both ways.
As a side note, I have also heard that even sexual orientation can/do change as well. Again, I am so confused and puzzled at this because once again, most people who are educated in this subject would disagree with that previously said statement. Yet I have heard people on here and read from endocrinologists that even say that sexual orientation can possibly change once hormone replacement therapy is initiated. Again, is it possible to change this at will or must we be manipulated by something else, such as hormones, to do that? Or is it impossible for this to change as well? Is it wrong for me to ask? I am merely curious and wanting answers if there are any, to my questions.
You hear about in the news section on here, at Susan's, about animals like frogs, being able to change genders at will. If we are the most advanced and intelligent species we know of, as scientists claim, how come we wouldn't be able to do that ourselves? And if we can, is there a way to do this intentionally without being coerced or through painful techniques such as conversion therapy?

I have so many questions its keeping me from going to sleep.....Imma bout to burn yet another real hole into my skull from this....
Thanks guys.
