A few days ago, I called my GF “mod” by mistake when I was asking her to do something for me; I didn’t even notice that I uttered that word in the moment, she had to point it out to me later on. The only other incident of this occurring was yesterday, where I accidentally called her “jannie” during sex instead of saying her name. It’s only happened twice and in my opinion it’s no big deal whatsoever. I’m only bothered as she keep bringing it up once in awhile, but I don’t see any reason in discussing it. I just want to tell her drop it without upsetting her.
