There is such a range among us, in size, stature, facial characteristics...I don't think its possible to make a blanket statement. Some of us just don't feel that the person we see in the mirror can even begin to present publically as female. Others can blend in but closer observation may betray masculine physcial traits, and some lucky ladies look totally feminine. In the end all that matters is that we are comfortable with ourselves and the situations we are in...if that means occassional dressing for ourselves (and our SOs) at home, spending time with others in safe gatherings, or being fully out there.
