It's an odd question: there are, it seems, thirteen different sexual indentities.
For example, considering my case:
1) after castration my body isn't a male body anymore;
2) but yet a little adrenal production of male hormones kept my sex drive still partially functioning, even at a very minor level and with serious changement (blood tests seem to confirm that);
3) in the most part of my sex-life my "role" in the game was more female-like than male-like...
4) so i'm not a physical male with partial male identity and male hormones but a female-like personality; i'm not a proper transgender in any case; so i think that "genderfluid" could be a proper definition.
