I don’t think there’s been any surgery involved, in fact I think the point here is that this “girl” has a penis.
When did they redefine transgendered? It used to be the term transgendered was reserved for freaks like Chaz Bono and Bruce Jenner (once he completes the surgery) that actually have surgery to try to become the opposite sex. What this “transgendered” male really is, is just what used to be called a cross dresser ala Ru Paul.
