This is a really good question, and I’m hoping that my perspective can help.
There are lots of things about me that feels less masculine than I would like (aspects of my body, mannerisms, etc).
Even as someone AMAB, I have always had the issue of not looking or feeling particularly masculine, because we’re told being masculine is a bunch of specific things. That ends up leaving massive swathes of men thinking they’re weird instead of who they actually are.
Maybe that can help reframe your thought patterns more toward “men have hips like this, and men feel this way,” because both are true. It’s not you, it’s the weird social pressure thrust upon us about what a man is.
