LimeKiwi what you have is a sense of self.
You will not answer. But I will ask anyway. If you can not define the 'what it feels like to be a woman'. Why are you so sure someone who was born and lived as a man, can define it and know what they are feeling? How do you know they are right? Feeling like you want long hair, or wear a dress or heels is not feeling like a woman. Lots of women do not do these things and are still women.
If being a woman is about biology AND this feeling of being a woman, why cant trans men simply change sex by feeling it.
You claim you know people can not change sex. Yet claim trans women become women. How? If its biology AND this mystery feeling, trans women are missing the biology half so therefore can not change sex. No matter how much they feel they can.
The previous pp (man) who talks about his testosterone etc is talking about social influences. Not the biology of being being a man.
The wiki link about Brains, is simply not true. There is no proven difference between the brains of the sexes. It may seem interesting to you. I love reading about polytheistic religions and the stories of the gods. I find how they are linked to creation very interesting. But they are just stories. They are not true. My feeling that they are interesting or that they explain creation in a non scientific way, doesnt make them fact.
I have a sense of self. Not the sense of being a woman. I feel like me. I know that I reject many gender stereotypes and embrace many others. Gender stereotypes are a social construct. I manage my anxiety by spending 3 nights a week, fighting. Despite being told it's not lady like. People who know me at work and see me in dresses, make up on and hair done are surprised I am also a fighter. All my hobbies are far more popular with men than women. I may wear a dress for work tomorrow. And Jean's and a mans hoodies the next day, again in work, depending on what I am doing.
I am not gender fluid. I am not identifying as a man on the days my clothes come from the mens section and a woman on the days I wear a dress. Nor does my sense of self change when I wear mens clothes. I just like mens hoodies.
I still a woman, because I was born.....a woman. If I spent my entire life in Jean's and mens hoodies, I still would not be a man.
Woman means adult human female. It's purely a biological fact. Feelings do not come into classification of sex.
