Dude has beanies and a weenie.
They knew he was a guy.
No; this person has Swyer’s syndrome, an extremely rare genetic disorder. They are born with external female genitalia, no weenie.
Also, the beanies never dropped so they do not appear on the outside.
By all outward appearances, they are a female. It took genetic testing to confirm XY chromosomes.
Not everyone is born XX or XY. A small percentage of the population has XXY, XYY, and X/partial X, etc.
Supermodel Hanne Odeile has Swyers.
