I'm a female-born and identified partner, wife, girlfriend, squeeze, lover—you name it—of a Transman (FTM). After spending his life stuck in the wrong body, he's transitioning to become the man he has always been. This is our journey from my point of view. Right now it's anonymous so if you know us, please respect that. But we both really appreciate comments.
It doesn't take a rocket scientist to figure it out: If you're a man and are born in the wrong body, it would feel wrong. Every day. I completely get it. Intellectually, at least. But I also admit that I don't empathize completely (different than understanding) because I've never felt 100% identified as a woman. I did take ballet. But even when I did, I always wore all black (a requirement of the school) and more to the point, wanted to be a male ballet dancer, who wore his tights outside his leotard and got to jump and leap. I was muscular and loved it. I also was a tomboy and I also played with Barbie. I guess I was always down the middle somewhere. So when people say, imagine waking up one day and discovering you were in the wrong body and how horrifying that would be, I understand. But I can't totally relate. I think if I woke up one day and was in a man's body, I'd probably be OK with it. I'd miss being a woman. But I don't think it would feel completely wrong. For me. I think gender is like sexuality. We all fit somewhere on the spectrum of how female or how male we feel. Like the Kinsey scale. And I respect that if you're at the far edge of male and find yourself in a woman's body, it would be pretty Kafka-esque.
