I did get a major freaky look from one guy once, I was in dude mode about three months on HRT. I have no idea what that was about.
During my first attempt at transition 20 years ago, when my hair was quite long but I was dressed male (with a bright paisley shirt) I had homophobic abuse hurled at me walking in the street by two idiots in a passing ute.
I started a Shiatsu course around that time, and ultimately became quite involved in the college and clinic there. Several years after I detransitioned I told one of the guys from the college about my trans history, he had been an assistant teacher on the night of my very first class there, and he said that explained why they "couldn't work out if I was male or female that night" (I was using an androgynous name)!
Also during that time, close to my decision to detransition, I had just had my hair cut short at the back. As I got off a bus I overheard two women (deliberately being biatches) saying "is that a guy or a girl"? Obviously an intended slur but I'm not quite sure how they meant it. I just ignored them.
