Someone once told me on a topic totally not related to gender or sexual orientation, when I said that I did not understand. I was told that I should be grateful that I cannot comprehend or understand, because that would mean that I would be either like that or capable of that.
The more that I think on the statement told to me, the more that I agree with it. I had a similar statement told to me on a recent visit to check my vision. My opthamologist told me that I was partially color blind. If I remember correctly, he said blue or green or something like that. I said that I see colors just fine, I really do. So I asked him how does that color look compared to what I see? He said that you cannot really explain color. You have to see it, or in this case feel it.
I have tried to explain gender incongruity (that is a better phrase and will be the accepted phrase with the new standards of care coming out, not GID), but my effort was like trying to explain green. People can kind of get it, but not really.
As I am feminizing, I am at peace with myself. When I was younger and before electrology / laser, I could not look in the mirror. That would freak me out. Seeing the hair grow from my face, not to mention a masculine face, but especially the hair, was mortifying. I hated to go to the dentist, because the dentist would see the hair coming out of me. Needless to say, I hated the sound of my voice. I could not listen to my voice without getting freaked out too. Now that I am learning to raise my voice, I am okay with it, or better than before, and getting rid of my facial hair (etc.) was a godsend.
I am not sure how to advise on that.
I would be interested if someone finds a way to "explain it", but I am not having much luck. Great question.
