You make some very good points and once again these are part of the overal thinking that "you were a man, how can you" series of questions.
On your first point, if you had a full abdominal hysterectomy, would you stop having orgasms? If you were born without a uterus, would you stop having orgasms? Of course not.
Do I have have vaginal contractions? Yes of course I do, I have exactly the same muscle structure as a natal female. My muscles contract the same way as any other female. I have clitoral orgams, I have vaginal orgams and I have blended orgasms, and there is no correlation between those and male orgams, they are completely different. My vaginal canal contracts in the same way as yours, becomes lubricated the same way as yours, and I have the same risk with thrush and BV as you could have. The only thing different is I have no cervix, but neither does many women who have lost theirs to cancer.
The brain of a post-operative female is the same as a natal female, the dopamine receptors are identical. The male and female human being is identical apart from one thing - hormones. The more estrogen there is, the more the brain feminises.
In regards to your followup question, I was born with a DSD, I did not choose to be classed as male. Even before transition, my testosterone levels were the same as a natal female. Part of the problem here is the "them and us" attitude. The hormones we have at puberty merely give us our secondary sex characteristics, which means the only thing I cannot do as a post-operative female is give birth naturally. But that will be possible in the future, as science is already growing uteruses and ovaries from stem cells which will be implantable back inside us. If I had wide enough hips I would be able to give birth naturally.
To say that I can't have orgasms like a woman and don't have the epistemic standpoint is both hurtful and borderline transphobic, but I will take it, as its a viewpoint that has to be addressed. I have always considered myself to be female, I had treatment for a condition to lead a somewhat normal life, but because of a large amount of misinformation and misunderstanding in society, you always assume we were men and are still men and can't possibly know what it's like to be a woman.
What happened to feminism and equality?
