What female spaces? Where/Who are these men flaunting their beards and erections?
My young friend would happily tell you that she is female. Her development simply went wrong when she was in the womb in the same way that other birth defects can occur. A simple hormonal error at the wrong time and she came out with a male body. Fortunately we can now correct that birth defect with hormone treatment and surgery, just as we correct many other birth defects.

Here is another filming in a woman's loo
Female spaces are places where women have traditionally gone to be away from men - usually because we are vulnerable. Changing rooms, loos, hospital wards, DV refuges, that sort of thing. They also allow women from religions that don't allow the mixing of sexes to have lives outside of the home.
As I say, I have sympathy with your friend - honestly I do. If she really believes that she is a woman, however, she will understand that there is a need for such places, and why.
