Switching is not inherent, like dominance or submission. Switching (and the act of being a switch), comes from the necessity or desire to fulfill a role outside your norm.
This is not actually true.
I'm not even angry, I'm being so sincere right now
Even though you broke my heart, and killed me
And tore me to pieces
And threw every piece into a fire
As they burned, it hurt because
I was so happy for you!
