I'm AMAB cishet, but I've been struggling with understanding my gender vs my sex. I'm very comfortable with my body, including by sexual characteristics, but have never felt a strong affinity to the male gender. Is there a term for this? Everything I look up includes some kind of body dysphoria, which is not something I relate to.
You might be experiencing social dysphoria or profound discomfort with patriarchy. We live in a violent, anti-woman society where men are expected to dominate and violate women. Even if you are happy being in a "male" body, you might not be happy with the role and expectations of being a "man".
