I was neither gay, nor feminine. I think my old self was always about the suppression of my emotions and desires.
I did my normal, deep voice and tried to mimic Arnold Schwarzenegger. It wasn't until I started transitioning that I did anything else with my voice.
I was visibly not a woman, but I wasn't manly really, either. I was basically a gender-less pack mule. I did things, to others they may have held some connection to gender/sex, but for me, they are just things I did.
Aside from that, there have been plenty of occasions where I said or did things that would make someone's eyebrows raise in questioning. Like when I was real young and I told my mom, "The only thing keeping me from being a woman is my penis" Later in life, I even tried to force myself to be gay(male/male) because I thought it's what I must be- I was utterly blind to who I really am.
Also, I love my voice, and it's what pushed me to really reconcile with my feelings. I may not have began transitioning if not for my femme voice.
