Yeah it actually weirdly suprised me when my cis SO said they couldn't really understand what the big deal was about my gender for me, and they said they wouldn't care if they were a guy or a girl, it's just not important to them. I guess our experience is pretty strange and alien to cis people which is weirdly validating... before my egg cracked, even then I felt like I understood/identified with trans people because I had always kinda wanted to be a girl but just told myself it was impossible
