I personally dont believe gender dysphoria to be a tenable position however.
How can you separate gender and sexuality?
I think this is where the physiological effects override the physical effects of sexuality, its like the timeline is off and the mental timeline and the physical growth does not match .
So this kid is a hetero female trapped in a hetero male's body?
That sorta limits our options a bit.
There have been some studies that seem to give merit to embracing the homosexuality angle and go that direction instead of all these "treatments".
