And If you're lucky you are one of those people born with both genitalia, and sort of have a neutral appearance between male and female.
Hermaphrodites are actually really interesting. I can't remember where I found it (Although a google search will probably turn it up), but I read this online sort of biography/study of this one hermaphrodite throughout his life.
I think he lived for about 60~ years.
Anyway, as they go through their lives they, or atleast he, had his hormone balance change.
And this biography had pictures of him, and throughout his life his face and body kept fluctuating between this more feminine version and a more masculine version of himself.
I think over all he spent more time as a feminine person (so I should probably refer to him as her, but I won't for simplicities sake).
But it was really interesting, but also rather sad. Through childhood he was feminine for some time, but was sometimes kept with the boys and sometimes kept with the girls. And I think he left school as a feminine person, but then went straight to college where he started to grow more masculine, including a beard I think.
But it was certainly a little bit traumatic on him, because he had gone from being more girly and having female friends, to suddenly being a rather masculine bloke.
But throughout all the changes, he has a clear and definite facial structure. So if you knew him, you'd definitely recognise him in each of the pictures, but you could tell when he was more feminine than masculine or vice versa.
