Wrong! The hip bone is the only gender specific bone in the human body--and there are only two shape types, determined by XX or XY chromosomal composition (rare instances of intersex people with three chromosomes will have the dominant combo), so until you can surgically swap out hip bones without screwing up your skeletal structure, there ain't no such thing as a transsexual, merely mentally ill transvestite self-mutilators. (And for the record, I am ultra mega super straight.)
