Most of these mannerisms are learned behavior. I used to watch cis females and study how they walked, stood, talked, gestured, etc. What I've learned is that overall you simply soften your physical presence. Walk and stand with your hips. Swing one arm when walking, stand lose, with a knee bent, and a hand placed backward on your hip, for example. All this takes is some practice. Not all cis females do this, I know plenty who walk and gesture like men. The point is, be subtle and relaxed. Look like you are relaxed, not ready for a fight. Over gesturing is just learned, habitual behavior. Soften your presence. Voice issues are a bit more complex. But, practice makes perfect! Good luck sweetie. 🙂
