My GF [31, me 31] is basically giving me the same shit test over and over...

An example she texts. "If the power goes out you and your roommates are welcome to stay over, you guys can take the couches and draw lots for who stays in my bed."

My reply: "It will be a drawing of lots to the death... kings will die, empires will fall, worlds will collapse into the void!"

I am at a loss why she keeps shit testing me with similar sexual themes despite that I am getting better at agreeing and amplifying.

At what point should I call her out, is calling her out even a good thing?
