Gay & Lesbian brain scans also show the same thing. So either all gay people are really trans, or it's just an indication of your sexual orientation.

Gender dysphoria is suggested to be a consequence of sex atypical cerebral differentiation. We tested this hypothesis in a magnetic resonance study of voxel-based morphometry and structural volumetry in 48 heterosexual men (HeM) and women (HeW) and 24 gynephillic male to female transsexuals...

You're either a female with a hormonal issue that causes a masculinization of your clitorus, or a male who can only partially process androgen so you end up with a partially developed penis & scrotum. No one has both a fully developed penis & vulva.
