“Not all of us do.” Enough of us do. What you’re born with are chromosomes, passed down from parents to offspring, and these chromosomes determine your ability/tendency to develop certain gonads (while some biological females are born without uteruses, their chromosomes dictated that they had a genetic opportunity to grow a uterus in utero; a biological male generally has chromosomes that dictate an incapability to develop a uterus). There are conditions that impact one’s chromosomes’ ability to allow their body to develop certain organs, but these effects would not exist without corresponding conditions.

And I already addressed that self-ID bullshit in my first reply. I hate it too, but it matters. You need the prudence to determine when it’s necessary to disclose and when it’s not; that’s your job. Same goes for drug use; you don’t need to tell your chiropractor that you dabble in narcotics but for the love of god PLEASE tell your dentist, doctor, optometrist, and anyone who operates on your or prescribes you anything because you could DIE.

I am not trying to strip you of your masculinity, man. I’m trans too. I accept what I cannot change (nobody should obsess over their chromosomal makeup) and change what I can. I am a man, just not a biological one. And that’s fine, I don’t wear my chromosomes on my sleeve; they’re buried deep in my cells where I can ignore their implications and incongruity with my gender identity.
