I look like a metal guy even biker sometimes. I got mammed two weeks ago at Costco. I have female manerizms, carry a backpack like a purse, had sunglasses on my head so cannot see balding, I get mammed at least twice a month and am totaly not trying. If you are, feel, and eminatate female there minds will see it and not see the real matter in front of them. Ever look at a chain link fence and cannot tell how far away it is? He saw female manerizms in his perifural vision ( the way I carry myself through manerizms and confidence) when I was no less than 30" from him he said looking right at me ,"have a great day mam" I said thankyou in my bad female voice and he did not correct himself.
I was not trying to be female, or passable, I only be myself and where boy clothes.
So find your true self and be that first. You will see even looking like a guy people have a hard time seeing it without a good long look.
The natives could not see Columbus sailing to the caribian islands for three days because they did not know ships like that even egsisted. They only saw the water ripples. ( so I have herd) kind of a medaphysical thing.
Self confidence appears to be more passable than physical changes , sometimes.
Hope this helps, Angie, aloha
