I'm bi and have been told that I have a deep voice but the way I hear it makes me sound pretty gay I'm also pretty sure that the pitch switches randomly.
So to answer the question I really have no clue... my voice is naturally manly at times I guess.
I could go pretty deep, but I never use it because it sounds forced to me. People think I "fake" my more feminine voice, but why the hell would I spend all day every day faking a voice?
My voice isn't what I'd say high pitched. It just sounds really young. I'm 25 but I sound like a teenager. It doesn't help that I have an incredibly strong Californian accent and have permanently engrained "bro talk" in my culture. My voice stopped getting deeper when I was like 16 for some reason. Probably all the drugs I did back then
