I do believe society and doctors can be sexist to a point...
In my situation, I was denied a mastectomy and hysterectomy because I was young, healthy cis-female, in the doctor's mind. The doctors feared I would regret the surgery and that if I desired to have children, that I wouldn't be able to (sterile from surgery) and they would get sued. Pfft, puh-lease! Having children is on my NOT-to-do list because it is a tumble down to Dysphoria-land for me. No thank you. I want to keep what's left of my sanity intact.
Y'know, it's not like the sexist notion is that all women experience the maternal desire and drive to create a family, that all they exist for is to fall pregnant and give birth to biological children is not at all insulting to the diverse individuality of women everywhere.
There was also no "medical" reason for me to get a mastectomy or hysterectomy, despite that I was suffering from intense dysphoria and depression since puberty began, despite that I suffered violent mood swings prior to my periods - I strongly believe I was experiencing Premenstrual dysphoric disorder, just it went untreated because my symptoms went ignored and treated as "normal" PMS. Getting swarmed with intense suicidal tendencies two days before my period hits every single cycle that I begin to pick up the pattern leading up to it is definitely NOT normal! It was extremely debilitating and it took a toll on my relationship with my family, friends and worse of all, my mind. It was no wonder that suffering from PMDD for the many years of my adolescence that I struggled to see any future for myself.
I also feel that asking the doctors to remove my female genitalia, I suspect this caused discomfort within them because what body would I have afterwards? It certainly wouldn't be female nor male either. Mind you, back then, I wasn't thinking that far ahead, I was thinking, "Great, the sooner I can get these things off me, the better I will feel." than "Hm, what sex will I be?" Either way, the decision regarding my body was made for me by doctors - against my will. I had no say in the matter and I felt that was incredibly unfair because at the end of the day, it is MY body, if I cannot be allowed to modify it, what's the point of calling it my body if I cannot change it - especially to elevate dysphoria? If doctors are so concerned with getting sued, I will sign a letter or a waiver - I would not have to because the likelihood of me experiencing regret after the surgery is very slim. I had thought about the surgery for many years, even dreamed of it for many nights.
Funny how if you identify as a man, they will send you to a gender therapist who will write letters that will allow you to access the surgery that was denied to you as a biological woman because, oh no, we cannot remove your breasts and uterus unless you have cancer! What if the breasts and uterus may have well been cancer to my MIND? Nobody cared about enough about that, did they? They just looked at me like I put my head into a bucket of water and asked if I was wet. Why is a woman saying her breasts and periods cause her depression? That is not normal, she should be happy with her breasts and it is normal to be sad from periods - women don't particularly enjoy getting them anyway! That is what I think the doctors would be thinking to justify my behavior and conclude that I am female, just a very confused one.
It's a messed up society we live in. Doctors will find excuses and justifications for anything that goes against the binary system. God forbid, should someone have the right to modify their own body if they have been proven to be of sound mind, aside from experiencing distress from the said body parts they wish to remove.
This was probably severely off-topic - if it is, I will delete it.
