Yes, I understood Aldo perfectly. I was just under the impression that Tony had been born "trans".
I don't think that's what "trans" means. What you seem to be referring to, being anatomically in between the "standard" sexes or having attributes of both, is called intersex. Transsexuality is having a psychological gender identity that's the opposite of your anatomical sex, with transgender individuals often undergoing sex reassignment surgery to bring their bodies in line with their gender identities. One can start out with an entirely female anatomy but undergo surgery and hormonal therapy to change one's body into a male form, although the "package" will be largely cosmetic. Tony -- or Antonia, originally -- may have been born trans in the sense of always having a masculine gender identity, but that doesn't require him to have been born intersex.
