At work I presented as male but my colleagues obviously suspected something.
An early example was a female colleague saying
"From now on, I'll call you Manly D...".
I said
"I'd rather you didn't. Some people might think that you are being sarcastic."
She replied
"Do you think I wouldn't be?"
During my next job, the ladies called me "Nana" because I allegedly looked like Nana Mouskouri. If it was just me and women in an office, a male colleague would say "Cheerio, ladies" when he left the room.
At my last job, a female colleague came right out and asked me whether I ever wore women's clothes. I was flustered and replied "If I did, I wouldn't tell you."
I think that I was wasting my time and hurting myself by presenting as a male at work. However, most of my life was not spent in modern Britain but in very conservative countries in an even more conservative past. Also, my mother, whom I loved deeply, said that she despised me after I was recognised while wearing women's clothes in public.
