I (cis woman) went through a period recently where my gender was being challenged. I’ll spare the details, but every time I pictured myself in a masculine context, whether that was topping, dressing more masculine, acting masculine, I still always saw myself as a woman in those contexts. I can’t picture myself without my femininity, with he/him pronouns, etc.
I’m a cis man who questioned my gender for a while, and similarly to the other person, I just couldn’t view myself as a woman. Feminine pronouns didn’t feel right, and I like my body as it is. That said, I still really enjoy feminine things, like the clothes and makeup, but I can’t see myself as anything but a man
