German girls are kind of annoying in bed. like stop shouting out your age loudly, it's really turning me off
Is this supposed to be a joke about age?
Oh, it seems like you got it. Not a lot of people get this one.
While its clever to use the German word for "No" to make a joke, the joke is about having sex with underaged AND non-consenting girls and that's extremely concerning. I really hope these aren't things you actually do and that you won't make inappropriate jokes like that in the future.
