Background: I'm living in another country and taking classes to learn the language here. I have a LTR here, of about a year.

The other day we were hanging out, and I mentioned to her that my next language class would be covering vulgar words, and that I was looking forward to the interesting lesson. We had a laugh, made a few jokes, and that was it. Several hours later we were getting into bed and I said in her language "show me your pussy." She instantly made a sour face and said "wait, you're not going to say that to your teacher, are you?" I interpreted this as a shit test, so I replied "Yeah I am! And she's gonna show the whole class her pussy!" So she of course got cranky but I mostly ignored her and fell asleep.

I didn't think anything was strange until the next morning, but she was acting very distant. Not like she was intentionally trying to ignore me or piss me off, but more like she was sad. So this is making me question whether it was a shit test or comfort test. She eventually got back to normal, but most of the morning she was just....off.

Anyway, does anyone have an opinion on this? Was it a shit test? How was my response? Any suggestions for how to respond when you're not sure it's a comfort test or shit test? Am I thinking too much about nothing?
