Alesha, I understand your concerns quite clearly. From what I see, being 'read' visually is highly unlikely. Therefor, I suggest some voice coaching - with a lot of practice you will be able to do it quite convincingly.
For me, it's not really a big problem. We don't get out together often, but when qwe do, it seems to work well. Can't say I've ever had any nasty comments or funny looks.
Oh, and Lorileah, some people's prejudices are to them matters of choice or serious issues. What works for you may not work for them!
