For me, this is one of the most enjoyable parts of exploring my female side. Why? Because when I use feminine mannerisms I get to FEEL feminine. That is gender euphoria.
I use every opportunity to practice my walk, my arms, hands, posture. Having a purse gives me something to do with my hands, so I don’t miss the pockets as much. Right now, though I’m in jeans and alone, my knees are together out of habit. I appreciate zoom because I get to see my face and gestures. I notice my “11” and try to relax my face to eliminat it. I look for my RFB. I even “point my toes forward” in the bathroom, as one ciswoman admonished.
I’ve often thought of conducting a “Girl Mannerisms” class to share my observations. Any interest?
