She teaches me that I am a natural bottom. I learn I can take almost a whole fist with no lube.
I learn this in 10 seconds.
She convinces me that I can't be trans because I use my penis during sex. I go back into the closet because that makes sense.
She assumes the role of domme. I assume the role of sub. I learn that I'm too loose to go walking for a mile with a plug in my ass.
My symptoms get worse. She notices. She uses it against me. I learn that BPD is evil and nasty and since I am not evil and nasty it can't possibly be me.
