I was attracted only the girls. I was never gay.
And transitioning haven't changed that.
I'm sill want to date girls, trans or cis.
So it is really a conservative myth that people become gay.
People can only come out of the closet.
Being gay is mostly orthogonal to being trans.
Many gays just transition or cross-dress to attract mates.
They do that not because they want to be women.
They do that because of others.
