My wife is a self described sexist. I tend to agree with her assertions that men do X, Y & Z, and women are A, B & C.
We all are raised with prejudices, or expectations. As a woman you expect men to have a set of attributes. Men tend to expect a set of attributes of women. Just the way it is. No matter how open minded we like to think, these feelings are often deeply seated.
My wife has also said she "cannot think of me as her husband with those bumps on my chest". I primarily present, live and work as a male. I care for as much, if not more, as before I undertook my journey. I'm the same person, yet far different.
Physically, I am not the same person I was some.... almost 40 years ago, or 5. I understand her her problems. She understands mine. "Maybe if you wore a Tee Shirt". Yes, she wants her man, No, she doesn't want a woman.
It is OK. Your feelings are valid
BUT... the primary reason my wife are still together (and alive) today is due to the difficult open and honest discussions
