Hi there,
I hope this is not off thread but I am always surprised that more mtf's don't realise how important the voice is in passing. I have come to the conclusion that if your voice appears female then even if you have some male looking traits people will see you as female. At least that has been my experience. So the voice is just and perhaps a little more important than say facial surgery.
When I was just a year into my transition three late teen boys passed me while I was on holiday and I heard one say to the other young men that's a ->-bleeped-<-. I was so mad I turned around and said, "excuse me, were you just talking about me?" One of the other young men said, "my friend said it to me and to be honest I don't know." I said, "Its really rude." several times, while the other young man by then was shuffling on his feet, looking embarrassed. In the end all three apologised and I walked off satisfied. I think it was my female voice that actually made then think in the end that I was female.
The only occasion I have had such a thing. Still I got an apology, lol.
