I struggle to hold frame.

If a woman says something that unexpectedly disrupts my frame, I usually am shocked into silence for a little, and I believe my facial expression conveys panic, because she often apologises for being so mean (while below the table her pussy dries up).

I haven't encountered a solid formula for how to maintain frame. Even upon reflection, I have to think really hard to work out what I could have replied.

I have learned a few generic shit test counters, but this seems like a band aid on a wound that isn't healing. How can I improve my inherent ability to remain stoic and reframe smoothly?
