My observation is that secure women [as in attachment theory secure] and women who are very clear that feminine expression is a performance assigned to them and necessary for them to get by/succeed , but who do not identify it as their fortress- see and understand exactly what guys are trying to accomplish when crossing over. That said, my daughter choked up when she said I was adopting the pleasures without the burdens and confinements of being a woman is society!
For me the physical release of allowing my body to flow into the feminine expression is a huge need and wonderful part of the experience. I love the inner feelings and change in sense of mass and lightness on my feet. My wife used the same word prancing- since of course the walk is very much that of a show horse! It has its costs, like I would need a few milliseconds to get my heels off and fight the cave bear., and white dresses are really hard to clean, and people sort of wonder why I am not agreeing to the cost/benefit tradeoff offered me as a male.
I am also really aware of how and why so many women choose just to dress in neutral ways that don't exaggerate our sexuality. And aware that the general social approval of displaying feminine sexuality only extends to females.
To get back to your original question, I am aware when my feminine expression bleeds over into my masculine mode and usually I curb it. At that point I am more aware of the options that gender flexible men have- and I am more of the John Wayne mode- if I have to be a man I am gritty- - but more importantly I definitely identify as a woman so I'd rather express femininity from that foundation. That siad, I have inescapably morphed into a gentle and non John Wayne type of guy - and I am not sorry.
